Location: Ukraine  Challenge: Stfalcon.com's task was to create an SDK for Android and IOS mobile platforms based on Kotlin Multi-Platform for a crypto wallet. Solution: One of the tasks was to combine business logic and use the same code base on different platforms. To do this, we used Kotlin Multiplatform technology, which allowed us to use the same business models, processes, queries, internal data processing, and encryption on all target platforms. Combining business logic has allowed: use the same methods to obtain and present data; identical handling of errors and intermediate states. For example, high-precision digital values ??are processed equally on both platforms. Interfaces have been developed to interact with UI applications, the implementation of which will rigidly define states, data acquisition format, and errors. Result: We have managed to develop a ready-to-use SDK based on Kotlin Multiplatform. This SDK integrates business logic and encapsulates all internal processes responsible for encryption, storage, and authorization. Read More

Location: Germany The challenge lay in designing CopeCart client apps to act as a utility to monitor e-sales performance, allow account holders to set goals, and receive notifications. The main non-functional requirement was the smooth operation of the app. "The interface should be smooth", said the customer. Solution: Developing native applications for existing businesses has many benefits. First, it is the ability to scale the product, and secondly - its stability and efficiency provide the use of best practices in app development. Third, finding a specialist to support and develop the product in the future will not be a significant problem. That's why we chose to develop native applications for CopeCart. Result: The team fully met the client's need for an app that demonstrates a "smooth interface", regardless of the number of graphics tabs he activated in the settings. All pages are loaded asynchronously, the data is rendered animated. Read More

Challenge: To transfer all the cash desk functionality to the payment kiosks and to make them as convenient and easy to operate as possible based on the best principles of UX.  Solution:  An interface design for Credit Agricole payment kiosks was developed and detailed operating scenarios for various cash operations have been created as well as screens for all the possible errors and notifications. The design variants developed were tested on a focus user group. All the drawbacks and benefits revealed as a result of the tested user experience were taken into consideration in the final design variant. For the bank customers, we implemented authorization and the extended list of services. Noncustomers have quick and hassle-free access without authorization to the most popular services like topping up, cash deposits, and some others. Besides, the services for independent entrepreneurs were listed separately. Result:  The design from Stfalcon has fully satisfied the requirements and expectations of Credit Agricole and the team even went above and beyond the initial scope of the project suggesting custdev, which proved the design was ideally crafted.  The solution is now implemented on the client’s side.

Busfor is an online ticket sales service that allows you to purchase tickets for domestic and international travel. It works in Ukraine, Russia, Europe, and South-East Asia. At the early stage, we helped this company to enter the mobile market by creating apps for iOS and Android as fast as possible. Solution The main task was to provide customers with a mobile application for buying tickets, moving away from using a mobile browser. Initially, Busfor had a working site with an adaptive layout that supported mobile phones. In mobile apps we decided to use WebView technology — it allowed us to develop and publish mobile apps in the AppStore and Play Market in the short term. In addition to the site shell, we implemented authorization via phone number and sending notifications to the app. For example, a confirmation of payment for a ticket or a reminder of an upcoming travel. Outcome As a result, Busfor successfully entered the mobile market of bus ticket distribution. Now, the service brings together more than 5 thousand carriers on 20 thousand routes across Ukraine, CIS, and Europe. Read More

Triplook is a new service app in the sphere of tourism and dating with the elements of a social network. The service is aimed at helping users quickly find a fellow-traveler for long-distance trips or short vacation. Stfalcon.com has developed a design and a mobile application for iOS and Android platforms. Server-end portion of the app was implemented on client’s side as a convenient and well-documented REST-API. For instant messaging, we developed our own service for publisher’s event processing.  In our case, it is a core application which sends information about a new event (for example, notion about a new fellow-traveler) on the server. Realtime work service sends this even on the client: — by sockets, if the user is online; — by push notification or email, if the user is offline. The advantage of this solution is in its simplicity and independence from programming language or framework: the messages between the servers are sent by AMPQ-protocol. Messages from the server on the client are sent by WebSocket protocol (RFC 6455). Read More

SmartSeeds is a service connecting both cargo owners and cargo carriers in one system in order to complete mutually beneficial transactions on transportation of grains and oilseeds. Initially, it covers the territory of Russian Federation, but with time it is envisaged to work in other CIS countries too. This service integrates several types of users at the same time. From one sight there are grain owners and grain traders. They are interested in cargo delivery from the elevator after harvesting to terminal or port from where this cargo is sent to destination. One of the features of transportation process is the volume. Cargo can reach up to thousands of tons and it is necessary to have many trucks available. Also, cargo can not be in stock for a long time and has to be collected in time. Before the launch of SmartSeeds cargo owners that don’t have proper vehicles had to solve this problem with own efforts by searching carriers. Moreover generally more than one carrier is required to handle the transportation process in limited time due to big volumes of cargo. Read More
