The first part of the system is a mobile game that lets you predict, learn and earn Bitcoin. CLIENT NEEDED: We’ve joined our client’s team and together developed the mobile game. On the technical side, we were responsible for building the back-end of the app, mainly in Scala and Akka.  WE DID: The part of the app that we developed consists of the following elements:  Forecast module which evaluates bids versus the exchange rates every 24 hours,  Calculation module that counts each player’s score  OUTCOME: The app has reached 10 000 users (as of April 2019).

CLIENT HAD: Previous-generation system which couldn't cope with increasing message loads. CLIENT NEEDED: There were three main focus areas. First, reliable delivery of hundreds of messages per second. Second, an integrated billing module with a web front-end. Finally, covering new use-cases of the system, for example new interfaces, integrating with other providers. WE DID: Implemented a high-performance, reliable SMS message queue, with nightly stress/performance tests. We also developed a web application that allowed for checking of billing status. Also, on top of the system, we created an SMS-iMessage-like solution. You can read a case study about the project our blog! OUTCOME: Fail-safe and efficient system with high bandwidth.
