Our app processes a lot of rapidly changing real-time data. It connects millions of sports fans, enabling them to chat, share their bets, and be part of the action. This involves working with data from REST to WebSocket, combining it and presenting it to users in real-time. We are always refining and optimizing our development processes, using that knowledge in new features as well as refactoring old ones. We are always learning and exploring new things to make the best product there is.
