Open Source

As we strongly believe in open source culture, we do not only use open source tools but we also create them. Some of our team members are committers to core Scala projects such as cats. Below you can find some of our in–house maintained open source projects.

Besides organizing our own events, we also support causes that we like and actively take part in sponsoring, organizing and participating in community events. In the past we sponsored events such as Arduino Day, Microservices Hackathon or Scalar Conference. Our team members took part in many hackathons around the world winning some prizes ex. BattleHack, HackWAW, Tech–Crunch Disrupt Europe.
