The Back story 

Our appearance has a significant impact on how we feel about ourselves, our confidence, and our actions. At the same time, thinning hair is a broad issue, affecting 50% of men and women, leaving them with low self-esteem. Nioxin, a Coty Inc. sub-brand, effectively solves the problem of thinning hair by applying its 25 years of heritage and dedicated research. 

It all started when Romolo Ganzerli, Global Digital Marketing Director at Coty Inc., sent us an e-mail. 

“Hi The APP Solutions, 

I’m looking for a team that will develop a consultation web and mobile app for hairstylists and everyone with thinning hair concerns so that people can receive more personalized treatment with Nioxin products. 

Currently, I’m in Geneva, Switzerland, but I can come over to Kyiv to discuss our project in more detail.“

Romolo Ganzerli, Global Digital Marketing Director at Coty Inc.

Once Romolo arrived at our office, we started to dwell on the project’s goals and objectives and shaped the project vision.

How Nioxin Consultation Works 

Nioxin, one of Coty Inc.’s brands, is a market leader for professional salon products in over 40 countries around the world. The Nioxin Consultation mobile app aims to help professional stylists suggest to clients proper hair care, making the client’s hair thicker and fuller-looking without side effects so they can thrive with newfound confidence. 

To find out about the client’s hair care needs, the app analyses the client’s scalp and identifies the three signs of hair thinning (Derma, Density, and Diameter), each with innovative skincare-inspired technologies to address scalp and hair needs and deliver thicker fuller hair. 

Then, the Nioxin application delivers a complete program with personalized hair care products for a tailored treatment that works. 

The app also includes quick links to NIOXIN’s market-specific websites and salon finder.

Client’s requirements 

The client already had a design for his app and wanted us to do the following: 

• Create a web plugin and mobile app for both iOS and Android for professional stylists and their clients with thinning hair 
• Integrate a scalp and hair analytic tool and suggest personalized treatment programs depending on the client’s hair condition.
• Set up the logic throughout the mobile apps and web plugin backend to provide a quality consultancy test.

Project Goals and Objectives 

Our main goal for the Nioxin Consultation app was to suggest relevant products to clients and improve their hair condition. We needed to develop an intuitive mobile application and web plugin for salon professionals, empowered with a product recommendation algorithm that could be used not only in salons but also at home. 

Our challenges

Comprehensive architecture. The main problem was to set up the logic that would connect two mobile applications on different platforms with the server. In addition, we also needed to build a web plugin backend that would deliver relevant product recommendations. 

Tight deadlines. At the very beginning of the project, our main priority was to build the product’s architecture from the ground. In this way, we streamlined the project’s production in order to meet the deadlines. 

How we did it 

The client came to us with a ready-made UI/UX design for all app screens and very detailed technical documentation, so he required us to do the coding part.

For this project, we applied Scrum methodology since the project had particular tasks to be done, as well as estimated time and budget. 

• We started the project development by estimating the time developers would require for one or another feature. Then, we broke down all elements and evaluated time in iterations, two weeks, during which we would implement the project functionality. 
• At the end of each iteration, we ran a demonstration session to show the client our progress and receive timely feedback. Our team also had to send weekly reports to the client with a list of tasks done. 
• Having assessed the requirements of the project, our team worked on building the proper project architecture first, followed by mobile apps and web plugin development, alongside the project’s backend.
• After we implemented all functions for the first app release, we did a final demo with the client, received feedback, and implemented the required changes. 
• Thanks to detailed documentation, clear client requirements, and skillful mobile developers, we managed to deliver the project on time. 
• The development began around the middle of May, and the first project was released on August 1, so it took us less than three months from start to finish.

Interesting Features We Implemented

Client profile

The app enables saving client details in personal profiles, identifying hair characteristics, and adding DERMA and DENSITY photos. In this way, hairdressers can produce a seamless salon experience and have instant access to all client profiles registered to their salon.

Salon Management

Salon chain owners track the performance of their staff and clients’ hair improvement over time via built-in statistics. Whether it’s one location or multiple, salon owners have access to statistics of how their employees performed in regards to recommending a Nioxin hair care product.

Consultation Tool

Nioxin’s mobile apps, as well as a web plugin, include test-based recommendations of Nioxin hair care products that would be most fitting for the given client’s hair type. To identify the client’s hair condition, the app offers a short questionnaire and saves answers to keep track of the client’s progress.

Client’s testimonial 

“It’s a real pleasure to work with The APP Solutions because it never feels like a client/supplier relationship. In essence, it’s a true collaboration aimed at delivering the best possible experience to our users, on time and within budget.”

Romolo Ganzerli, Global Digital Marketing Director | Coty Inc.

The backstory

London is not only the capital of England, as we all know, but also a capital of fashion & luxury business that attracts millennial millionaires, fashion designers, and brands.

Once we got an email from Matthew, our client, who was inspired by our blog post about taxi-hailing mobile app development.

“Hi The APP Solutions team,
I have both an exciting and challenging project for you.
Can you develop a taxi booking app for the luxury segment?
Keep in mind that here, in London, the app will be promoted by fashion influences, like Virgil Abloh, the artistic director of Louis Vuitton menswear”.

We were more than excited about such an opportunity.

Client Requirements

After we contacted Matthew, we clarified more details about the project.

HYPR is a-first-of-its-kind supercar booking taxi app that works on the subscription basis in the London area. Its vehicle fleet includes Rolls Royce, Gelentwagen, Lamborghini, and other supercars, popular among wealthy millennials who prefer to rent cars than buy them.

Matthew already had several screens of his mobile app design, so he was looking for a development team that would build the code part for four standalone products, as well as back-end logic and stable infrastructure.

He also emphasized the limited time frames. We had only four months to develop the app’s MVP so that the client could show it to the commission of Transport for London(TFL). It was quite challenging to book an appointment in TFL, which is possible only every 6 months. We had to demonstrate the product and receive certification, so knowing the strict deadlines, we had no room for mistakes.

Project Goals and Objectives

• We needed to create a luxury taxi-hailing app that gives users the feeling of belonging to a closed community of VIPs. The concept of private membership clubs is pretty common in the UK.
• The app should operate on a subscription basis. Thus, every potential member should be verified by the Admin.
• We needed to build four distinct products, such as a subscription website, an Admin panel, driver and passenger apps, equally useful for all participants.
• We also needed to make the apps compliant with the Technical Solution Requirements of Transport for London.
• Find appropriate payment gateway for Subscription website and a develop custom price calculation algorithm

Our challenges

During the development phase, we faced the following challenges:

• UI/UX design. Since it’s a luxury product, our team had to make the UX very smooth and user friendly.
• Detailed documentation. Due to tight deadlines, our developers needed to develop a clear code without bugs from the first attempt. Thus, we needed to create super-detailed technical documentation and determine all possible user stories and scenarios beforehand.
• TFL compliance. Our technical documentation had to be compliant with the Transport for London Technical Solution Demonstration Guidance and Technical Documentation Guidance for PHO Applicants. Transport of London pays extra attention to features connected with lost and found property, complaints and compliments, vehicle details, bookings records, and private hire drivers.
• Four products at once. Apart from creating the Admin panel and Subscription website, we needed to develop fully-fledged mobile applications for Drivers and Passengers with geolocation, personal profile, estimated pickup time, optimize the road to avoid traffic jams, and make both apps work simultaneously.
• Price aggregation algorithm. We needed to create a custom price generation algorithm that would generate the ride price by analyzing multiple factors. The algorithm determines the ride price by combining the car’s rate, driver’s location, the amount of time the driver waits for the passenger, the passenger’s desire to extend the ride, ride length, and so on. In the case of the driver’s location being too far away from the passenger, we needed to develop functionality that would offer similar cars nearby and calculate the ride’s cost.
• Money refund logic. Since the app is targeted at the luxury segment, the first project release must work without bugs. At the same time, we faced issues with money refunds when the passenger canceled the ride. In this case, the money refund depends on many factors, including when the passenger hailed a car, passenger’s membership type, driver location, and others.
• Hidden phone numbers. Since the app’s users belong to a luxury society, they respect their privacy. Thus, we needed to hide real app users’ phone numbers and mask them with random phone numbers from the London area.
• Real-time geolocation. The app should always show the current driver’s position using GPS integrated into the mobile device. The main challenge here was to choose the right geolocation API because most third-party geolocation modules work with delays.
• Limited resources. During this project, we often compared ourselves with the team that developed the Uber mobile app. But, unlike the Uber team, we had limited resources, including developers, funds, and timeframes, making our mission to develop bug-free luxury mobile apps almost impossible.
• Bonus programs. At this step, we needed to develop the logic for HYPR’s bonus program, which included several user groups. The app awards some users with 100 pounds they can use for rides. Also, some users receive a free subscription for several months, while others receive a life-time free subscription.
  

One Solution, Four Products

We developed HYPR, a transportation platform that offers exclusive service of supercar hiring for its customers. The platform consists of:

Subscription site

A web portal allows applicants to submit forms for registration in the HYPR app.

Admin dashboard

A web portal allows Admin to view and manage Applicants and Customers, Drivers, vehicles, manage car models, prices, and review statistics from both driver and passenger apps.

HYPR App

A mobile application for Members, i.e., passengers who were approved for registration and can use the HYPR App. Members can hail a supercar, schedule the departure time, choose the available supercar model.

HYPR Driver

A mobile application for Drivers. Driver app users can sign in to the app, add car details, view all orders nearby, pick up passengers, and complete rides.

How we did it

Step 1. Make the apps compliant with TFL requirements

Firstly, our business analysts checked all Transport for London requirements concerning essential app features to make the project technical documentation compliant with it.

Step 2. Write technical documentation

Secondly, our business analysts, together with tech leads and developers, started to write technical documentation for the project, highlighting all possible scenarios and user stories for both driver and passenger apps. We also created the best possible infrastructure of the HYPR platform.

Step 3. Prioritize features and plan MVP

Thirdly, we analyzed all user stories from Technical documentation and prioritized the essential functions of both driver and passenger app for the project’s Minimum Viable Product (MVP). As a rule, we start all sophisticated projects as MVP so our clients can achieve the proof of concept of their business idea.

Step 4. Develop the MVPs back-end

Fourthly, we started to implement user stories and main scenarios for the passenger app, driver app, and admin panel. At this step, we also developed a Subscription website and integrated a payment gateway.

Interesting Features We Implemented

Payment Gateway

The HYPR application required a reliable and accessible payment processor to handle:

• Subscription fee management
• Ride payments

In addition, we needed a solution that would refund money on the different ride’s stages. Thus, we decided to integrate Stripe because it perfectly met the client’s requirements.

• User-friendly interface
• Merchant account features
• Multiple payment methods
• PCI DDS compliance + AVS, SSL, CCV features
• Flexible API

Google Maps and Google Places

Geolocation was another essential app component, requiring integration of third-party APIs for general map navigation, vehicle monitoring.

We used:

• Google Maps for general web mapping and vehicle movement monitoring
• Google Places to streamline the navigation and provide additional information regarding different locations

Data security

One of the client’s requirements was to make the app GDPR compliant. This meant that the app should meet strict guidelines for user data management, include transparent data use policy, and guarantee data safety. To make HYPR GDPR compliant, we used the following solutions:

• HTTPS, TLS, SSH for data-in-transit encryption;
• BCryptfor database encryption;
• DDoS protection;
• PCI DSS compliance;
• Activity Logging and Access Management;
• Limited access to the production database at the network level.

Our tech stack

• Subscription website – JavaScript, PHP, Firebase
• iOS passenger and driver Apps- Swift
• Admin Dashboard- Sonata and WordPress
• Payment gateway – Stripe API
• Geolocation and maps – Google Maps, Google Places API, Visar Maps
• Use analytics tool – Google Analytics
• Data Center for the environment, disaster recovery and backup site- Telehouse London

Team composition

• Project Manager
• Business Analyst
• 2 QA engineers
• Front-end developer
• 2 Back-end developers
• 2 iOS developers
• DevOps

Results

We nailed delivery of the MVP of two mobile apps, Admin panel and a website with subscription on time, Matthew presented our project to the Transport of London committee, who approved our applications for the London area. After the MVP launch, we entered the second development phase and integrated other features for the app’s public release. Currently, we continue working on the app, and soon we will release a new app version with more features for both drivers and passengers.

New HYPR’s release will include

• Alternative car suggestions with the same amount of passenger seats
• Driver mode will allow app users to rent a car and drive it themselves
• Convoy mode will enable users to book several cars at once

For us, working on the HYPR project was a better experience than riding all supercars at the same time.

The backstory

Ibiza is the mecca for nightlife enthusiasts. However, the pandemic has changed the way people attend night clubs. Due to restrictions, all clubs on the Island were closed to prevent a second wave of COVID-19. Thus, millions of party goers had to come to the Island and organize their parties in private villas.

In such circumstances, party enthusiasts were looking for an on-demand delivery solution to order their favorite food, alcohol, and groceries with no hassle.

Enrico, our honored client, envisioned this opportunity. There was also no intense competition or big players like Uber Eats on the Island. He managed to launch the product in just two months, earning his first customers and reputation before the season ended.

What is Alfred Ibiza

Alfred Ibiza is an on-demand delivery mobile app that connects restaurants, stores, couriers, and customers in Ibiza. The app allows customers to order from restaurants, pharmacies, and supermarkets, listed on the platform.

• The app charges you the cost of products and delivery services, and withdraws money from your credit card.
• Once you place an order, the app finds the nearest courier to deliver your order.
• The app also includes particular product groups, delivered exclusively by the company’s employees.
• You can connect via a restaurant with email and track the courier’s geolocation in real-time.

Our Goals

Our main goal for the Alfred Ibiza project was to build a platform that would simplify ordering and delivering products on Ibiza island and help party goers to receive their orders on time. We wanted the platform to be equally useful for business owners, couriers, and customers.

Project scope

We needed to design all the business processes that an on-demand delivery mobile app requires and ensure the final result would have similar features to those the most popular food delivery mobile apps include (such as UberEats, Doordash, Glovo, etc.).

We needed to develop a complete infrastructure from scratch for three mobile apps – one for buyers, for sellers, and one for couriers, that would work on both iOS and Android, a web-based admin panel, and a marketing landing page to promote Alfred Ibiza.

We were also responsible for the UI/UX design for all the platform’s components (mobile and web applications).

Our challenges

• Limited timeline. This project was not the first time that clients contacted us after being rejected by other development teams due to tight deadlines. In this case, we needed to build cross-platform mobile apps and an admin web panel for restaurant owners within two months.
• No technical documentation. The client came to us only with a business idea. Thus, we needed to develop project documentation in-house, which is the core of any IT project. For this, we needed to conduct a business analysis of existing on-demand food ordering apps, define their core features, and suggest technologies to implement them.
• Comprehensive payment calculation algorithm. The client’s business logic required building a complex pricing algorithm that calculated the delivery fee based on the product category and distance of delivery.
• Courier online geolocation tracking. Since most popular food ordering apps include courier services, we also needed to integrate live position tracking of couriers into the client app and an admin panel.
• Live-chat. One of the client’s business goals was to ensure transparency in communication between restaurants and customers. Thus, we needed to integrate a live messaging functionality to the app.
• Couriers provided by businesses. According to Ibiza’s regulations, products from Alcohol,Tobacco and Pharmacy categories must be delivered by the brand’s employee. To enable this option, we needed to empower the restaurant’s admin panel with the function of delivering their products without third-party couriers.

One Ordering Marketplace, Four Products

The customer app
The customer app includes the following sections:

• Home page

The home page is the first screen you see after opening the app. You can find different product categories, such as Food and Beverages, Alcohol and Tobacco, and Pharmacy. As a user, you can select the necessary category, browse the product catalog, select products, and order them.

• Push notifications

Once the order placed is approved by the provider, you service a push-notification about the new order status In progress, and another notification when the courier delivers your order.

• Inbox

You can exchange messages with restaurants and other businesses within the app using the built-in messaging feature.

• Manage orders

This section includes order history, which allows you to cancel or reorder products anytime.

• Add new order

Apart from the Home page, you can place the new order in the Add new order section. You can also select the Take-out option and get the order at the seller’s physical location yourself.

• Favorites

If you enjoyed a particular dish or restaurant, you can save it to your favorites and access them in the Favorites section.

• Offers

This section includes special offers and discounts from sellers and food providers.

• Settings

As a user, you can save your address, add credit card information, etc., in the Settings sections.

• Helps

Here, you can receive help from the platform’s admins anytime you need it.

• Reviews

Here, you can rate restaurants, meals, and couriers.

The courier app
The courier app includes the following features:

• New orders

Once the courier receives the new order required, one can accept or decline it.

• Map

If the courier accepts the order, the app automatically changes the order status to In progress. The couriers see the pickup and delivery address on the built-in map with the shortest delivery route.

• Order history

Couriers can access the history of completed orders in the Order History section.

The provider app
After login, all providers access their mobile application with the following features:

• Menu management

Business owners can add, edit, and delete products in their menus, upload images, change descriptions, and prices.

• Receiving orders

Once a customer places an order, the provider receives a message from the platform with other details, customer name, total order sum, and delivery address.

• Replying to customer reviews

After the customer leaves a review of one’s products, the provider can reply to the customer’s review.

• Live chat with customers

As the customer places a new order, one can connect with providers in the live chat and discuss order details.

• Placing and tracking delivery requests

After the provider approves a new order, one places a delivery request to the courier app and tracks delivery progress.

Admin panel
We empowered the web-based admin panel with the following functionality:

• Dashboard

Here, admins can count the total number of users, restaurants, current orders, and other platform stats.

• User management

As an admin, you can add new users, access their details, and block users.

• Category management

In this section, you can add new product categories, manage existing categories, and delete them.

• Order management

You can view new and completed orders, edit order information, and cancel orders.

• Promo cards

As an admin, you can issue promo cards that give customers discounts.

• Rating and reviews

You can add, manage, and delete user reviews.

• CMS management

Here, you can access your customer management system’s information, add, edit, or delete users.

• Helpdesk tickets

In this section, you can view messages from customers who need support on your platform and solve issues.

• Banners

Here, you can add, manage, and delete banners on the landing page.

• Manage settings

As an admin, you can manage user settings for customers and restaurants.

How we did it

• Step 1. Business analysis

We analyzed the most popular food delivery applications and created a list of selected features to integrate. We decided to build a cross-platform application with React Native, so both iOS and Android device users could access it.
We gathered our core technology expertise in on-demand projects and applied it to create an ordering engine to avoid building it from the ground up. In such a way, we significantly reduced the project development time and costs.

• Step 2. Business processes

As the client came to us with only a business idea, we were also responsible for developing and maintaining all related business processes. We made the project’s account on the Stripe payment system, a cloud platform for hosting the app’s architecture and other project-related services.

• Step 3. Technical documentation

We developed the project documentation for Alfredo Ibiza, in which we described the platform’s primary functions. The documentation also included user stories on how the platform should behave in different scenarios, such as a money refund.

• Step 4. Four product categories

We were also cautious with different product categories and their use cases since they required a different delivery approach. Thus, we decided to divide app products into three major categories, such as Food and Beverages, Alcohol and Tobacco, and Pharmacy, to simplify the delivery calculations process and ensure orders from alcohol and pharmacy would be delivered by business representatives only.

• Step 5. Price calculation algorithm

Since the platform calculates delivery fees based on the product category (from 15% to 30%), the delivery distance and total project sum, we decided to work with an existing payment gateway and customize it for the project’s needs. For this project, we decided to use Stripe because it is a popular payment gateway that supports the main payment options, including Apple Pay, Google Pay, Visa, American Express, and Mastercard.
To make Stripe calculating custom pricing, we gathered main product categories and created calculating price rules first on Google Spreadsheets. Then, we agreed on the price-forming algorithm with the client and our developers made all the necessary changes into the Stripe code, so it met the project’s needs.

Results that we achieved

We managed to develop the Alfred Ibiza platform within just three months, at a total project cost of $70,000, 50-60% cheaper than the average development cost of a food delivery app.

The platform includes an app for customers, couriers, an admin panel for restaurants with only necessary functions. Besides this, we also developed a marketing landing page to promote the Alfred Ibiza platform.

How it started

When we travel on vacation, the last thing we want is to spend extra time at the hotel reception desk during the check-in procedure. Now, we have PassportScan, an app that allows travelers to register at hotels seamlessly via mobile devices and tablets. 

The story began when David Palo, CEO of PassportScan, was looking for an answer to a fundamental yet straightforward question “whether to develop an iOS or Android app for an existing software?”. 

To find the answer, he searched the web and came across our blog post on the subject. After reading our article, David still had specific issues that remained unresolved, so he decided to contact us and find out more about the mobile app development process.

Once we got in touch with David, he told us more about his challenges. David already had the existing hotel front desk software for document scanning and classification, but he needed an app for tablets and mobile devices that would automate the rest of the check-in procedures done manually by hotel personnel.

As a result, we started a long-term co-operation and developed a PassportScan app for iPads and Android devices, a web service for hotel employees, and a subscription web portal. 

What is the PassportScan app?

PassportScan is a SaaS for hotels, currently used by Mariott, Four Seasons, Hyatt Regency, and Hilton. The app turns the check-in process into a 30-second operation and streamlines data gathering using image scanning tools. 

By using PassportScan, hotel employees can scan a guest’s documents, let guests sign registration cards digitally, manage the information via the app, and send data to the hotel’s property management system or customer relationship management system. 

PassportScan helps to get rid of paper documentation and reduces the number of human errors in the client’s profile by leveraging optical character recognition (OCR) features and the integrated Address Validation Engine. 

Our goals 

• Develop an app for iOS and Android. We needed to develop an app for tablets and iPads that would allow managers from different hotels to log-in to the PassportScan system via personal accounts, scan guest documents, and send the data to the hotel’s database. 
• Integrate the app into the client’s eco-system. Each hotel has its own in-house system to track check-ins and information about guests. Thus, the app should send scanned data and other guest info to the hotel’s database seamlessly and error-free. 
• Build a data management system. Apart from scanning passports, users need a platform to manage data, set up owner and branch settings, payment information, and user access.
• Enable user payment. Since PassportScan applies a subscription payment model, we needed to create an e-commerce module for online payments via credit card. 
• Protect personal data. Since the app deals with sensitive data (customer data, document images, and biometric signature), we needed to apply advanced security measures and make the app compatible with new European regulations regarding personal data privacy, such as GDPR.  

Our solution – PassportScan app 

PassportScan consists of three main parts.

PassportScan Workspace 

Workspace is a web portal designed to manage apartment bookings in hostels and hotels. Workspace stores guest profiles, booking details, ID information, and signed documents. 

PassportScan Workspace keeps data received from

• A mobile PassportScan app
• A PassportScan desktop software
• Hotels PMS (Property Management System)

PassportScan Workspace supports integration with Oracle products, such as Suite 8 and Opera, to import and export data. The web portal also includes the support ticketing system so that hotel employees can get in touch with developers in case of bugs or system failures. 

PassportScan Billing System 

This is a web-based app for PassportScan users to pay their subscriptions via the Stripe payment gateway. Initially, users have a one month trial period. At the end of each month, users receive auto-generated invoices based on the number of scans and signs added to the system, and the number of gigabytes used. 

PassportScan’s billing system includes the following features:

• Billing details validation
• Credit card validity checking
• Online payments via Stripe payment gateway 
• Editing payment methods
• “Payment history” with digital invoices 

PassportScan Native Apps for iPads and Android tablets 

Native applications allow hotel employees to scan a guest’s documents with iPads and Android tablets, then send data to the Workspace.

Apps for both platforms include the same feature set:

• Search for available bookings in the PassportScan system
• Scan front and back sides of documents 
• Edit the guest’s details
• Digital Signature 
• PassportScan privacy policy 
• GDPR compliant Data Use Agreement 
• List with additional hotel services 

PassportScan’s check-in takes six steps:

Step 1. Hotel employee starts the registration/check-in process and finds the guest’s booking 

Step 2. Hotel employee updates guest info by scanning documents using the PassportScan app

Step 3. The app recognizes the image from the guest’s passport, captures the data, then classifies and verifies it

Step 4. Hotel employee edits the identified elements if needed

Step 5. The guest agrees with the privacy policy with the GDPR compliant Data Use Agreement 

Step 6. The guest puts a digital signature and may ask for additional hotel services

Our challenges and solutions

Architecture 

Due to the system’s complexity, we developed the project’s back-end system with a potential high load in mind by applying a microservice architecture approach that enabled the system with both vertical and horizontal scaling. 

In this way, the application is divided by functionality (vertical scaling), and each microservice can run as multiple instances behind a load balancer (horizontal scaling). Also, we achieved a more effective consumption of computational resources, since, under high load,  the architecture scales horizontally. 

The project’s core consists of 8 back-end services for reading, scanning, and saving documents, digital signatures, etc., and three public components:

• The Public API provides an interface to the back-end for a native application, as well as integration capabilities for 3rd party external systems
• The Admin panel with a dashboard for configuration management
• The Workspace, a web interface to manage the system for hotel staff

Security

For every type of app user, the system provides an authentication procedure with personalized credentials and password security provided by Admin. The system interacts with the outer world via SSL with 128-bit keys. Services without external connections, placed on the private cloud, are entirely isolated from external access. The system protects sensitive customer data by encrypting with AES 256 algorithm.

Tight deadlines 

The biggest challenge we faced was keeping tight deadlines during the development stage. The main reason for such a rush was that David and the PassportScan team had already scheduled presentations of the app’s MVP at several RoadShows and Hospitality conferences. Thus, there was no room for error.

We nailed the project’s release within the deadlines, thanks to defined Milestones, a carefully prepared back-end, and microservices project architecture. Thanks to microservices technology, we managed to develop several modules simultaneously, and the further module orchestration helped us to avoid any kind of server shut down. Thus, if any of the modules fail, other modules quickly help (less than 5 sec) to retrieve all the data.

Results

PassportScan is shaping the hospitality industry by showing how technology can eliminate routine tasks and paperwork for hotel employees. 

Thanks to clear project goals and timely communication with David and the PassportScan team, we managed to build the first app version in just one month from the project launch. We are proud to be a part of such products as PassportScan because they improve the world we live in today. Watch the video where we share our thoughts on the PassportScan project. 

Recently, we launched the discovery phase of the Self-check-in app for PassportScan to enable guests to make check-ins via the app with their own mobile devices. This is very important right now with the situation of the Pandemic of COVID-19, allowing the possibility of non-contact services in the Hospitality industry.
