„Flexiana helped us build new systems in our new micro service architecture. They were great to collaborate with and delivered value very quickly. I would not hesitate to use them again.”

Annika Gunnarsson, Product Owner, Zimpler

Developing a payment processing system

We help make different types of deposits and withdrawals from the backend to UI (full-stack). We began with creating microservices in Clojure and extending UI written in ClojureScript as a field of expertise. Furthermore, we started maintaining a couple of bigger Ruby projects related to deposits functionality. We also helped develop some parts of the system in Typescript and Go. Our work includes writing tests, fixing issues, proposing solutions, analyzing requirements for new features, integrating with external APIs. Development is based on the CI pipeline with integration tests so that each developer can deploy to production even a couple of times during the day. Most of the time we work as a separate team and make features from analysis to the release and use in production and sometimes we are part of other teams to speed up their features delivery. We use Kanban like tasks management.
