Client: Vsi. Svoi (the largest platform of Ukrainian brands)

Challenge: The client asked us to improve the project infrastructure and provide the opportunity to add new sections to the site. Stfalcon's task was to move to a containerized infrastructure with Kubernetes:

• increase the overall reliability of the infrastructure and the percentage of service availability
• simplify the process of making changes, ensure the identity of dev/staging/production environments
• speed up and secure the process of delivering changes to environments
• add new sections: Home and Decor.

Solution:

When building new infrastructure, IaaS Hetzner Cloud was chosen, which combines a favorable cost and high quality of services provided, and also has all the basic functionality required to build a modern and flexible infrastructure.

The business idea was separated into the main functionality:
Activities. Calendar. Timeline. In addition to information about users, the profile contains training guides, a guide for using the application, and useful resources from partners.

Result: The Stfalcon team managed to develop a user-friendly platform in which it is easy to find the most suitable exercises, build a training program and monitor your results, and the client received a system that is well monetized due to a flexible subscription system.

Challenge: To help the homeless change their lifestyle and acquire certain career opportunities. To create an app, which would provide more info about a homeless person. 

Solution: A mobile app on iOS was developed with a backend realized in the form of RESTful API. Symfony PHP framework, ready-made third-party bundles, and Stfalcon’s in-house developments were used in the process of backend creation.

The application, as well as the admin panel, written on the Vue.js JS framework, communicates with the server through API requests. 

Stripe payment system was successfully integrated into the app. More than that a new API Stripe version was used to comply with the new requirements of European financial transactions.

Result: A mobile app with a user-friendly interface, which helps to find out the information about the needy homeless people, help them reach their goals and follow their achievements and life changes.

Client: NIC.UA LLC, Ukraine

Challenge:

To make service more flexible and simpler to scale, so it could handle a huge number of our users.

Solution:

The frontend of a site was developed from scratch with API integration. A custom flexible dashboard was built and multilingual intelligent search using WebSocket and smart caching for optimal loading speed were implemented and  made compatible with the API for authentication and orders.

Special modules were created to be displayed in certain parts of the screen and landing pages for discount offers. The site administrator can now restructure each page without touching its code.  

Result:

The number of visitors drastically increased right after the redesigned site was launched. The smart search feature has helped to attract many new leads and sell a high number of domains.

Client: Stroitel, Special Equipment Rent Company

Challenge: 

To match the owners of special equipment, who provide it for rent with the clients in search of special machinery.

An additional challenge was to match the exact budget indicated by the customer.

Solution:

An on-demand equipment rent app was developed for Android.

The product solves 2 problems at a time:

It helps the special equipment owners - get rent proposals for their technical devices rent and those who need equipment for some special purposes can get proposals from the equipment providers.

The tight budget challenge was solved by substituting the backend part with a  BaaS solution. External services are integrated into the product with the help of Firebase and it also serves as a Backend to the solution developed.

Such an approach not only helped to save budget means but also to speed up the project release.

Result:

The app is already launched in test mode, it is already deployed in Google Play Market and has got positive reviews from the first users. They mentioned the application simplicity and good quality. Still, the problems are monitored to fix the solution failures in the future.

Client: COO, Food Teck, LLC/Balabing

Challenge: To develop an app, which will allow the users to place orders online and pay for them, the vendors to receive the orders, fulfill them and send notifications, and the client to manage it via a web-based admin panel.

 Solution: A mobile app for a food truck management company was developed. Both an Android and an iOS version of the app were provided along with UI/UX designs. PayZang payment system was successfully integrated into the solution as well as the SMS service for users’ notifications.

Result: App development is going on, the payment system is being tested, but the initial version has already exceeded the client’s expectations from the UX point of view.

Client: Elvia, Cyprus

Challenge: 

to make a discovery to give the Artist a platform where he can be booked for a venue to perform. 

Solution:

We filled out Lean Model Canvas with the client and made a questionnaire for venues and artists to know better about work, life, and thoughts of their cooperation from firsthand experience. We built proto personas and made CMJ separately for the venue and artist.

Result:

Except for prototypes for mobile apps, the client got the project charter where he can find all the results of our discovery phase, a description of our management and development process, possible risks, user stories, and the raff estimation of the project.

Client: On-Demand-Massage App

Challenge:

To help the clients order massage here and now.

Solution:

Interaction design, UI drawing, and client mobile applications for Android and iOS were created, as well as the applications for masseurs. The app has two main functions: receiving requests for massage in the nearest radius and notifying the service that the massage session is over. The fulfillment of orders and earned money statistics are kept in the app.

A backend and an API were developed for connecting mobile applications with the server.

The main feature of the developed user application was a quick order, besides there is a possibility to make it without registration which became a real advantage of the app.

Result:

A mobile solution, which connects masseurs and their clients in real-time.

Client: Bingebooks, USA

Challenges laid in the creation of mobile applications for iOS and Android platforms. The main functions can be divided into lists of recommendations from the authors of the service; search for books and authors; view information about the book: description, average rating, comments from other users, purchase offers; an audio player for listening to a demo version of an audiobook; reader for familiarization with the text version of the book; the ability to manage personal lists for the management of interesting or already read books.

Solution:
For app development, we chose the cross-platform Flutter framework. This gave us the opportunity to develop 2 apps at once, which significantly reduced the cost of the project in development, and supported and minimized the time for making changes. And as a bonus, Flutter makes it possible in the future to extend existing apps to the desktop: Windows, macOS, and Linux, at a minimal cost. To do this, you just need to adapt the design!

Result:
Users got an easy-to-use library of books wrapped in a user-friendly application with the most necessary functionality familiar to them from the web version of the service (plus, running at 60fps without slowdowns and incredibly smooth animations). And the client received a modern, high-speed product using advanced development technologies.

Client: Triplook, USA

Challenge:

Additionally, there is an option of choosing the fellow-traveler sex and age and opportunity of browsing resorts by countries and rate as well as getting detailed information about them

Result:

Creating a new service, which combines travels, dating and social media.
