BUX is creating a whole new stockmarket trading experience by combining concepts from gaming, mobile messaging and trading. We do this with a very small team consisting of 3 mobile and 3 backend developers. By combining more traditional technologies used in the financial world (Debian, Java, Spring Framework, FIX) with a modern Reactive Architecture leveraging the power of technologies such as Cassandra, ElasticSearch and ElasticActors we are able to release our product bi-weekly to the Android and iOS platforms.

In this presentation I will talk about the Reactive Architecture that we have built for our backend services. I will touch upon the communication protocols we use for our client / server communication but this talk is centered on backend technologies. Should be interesting for Architects and Backend developers, not necessarily from the FinTech world alone.
