Company Type

We aim for versatile and flexible teams with 4 - 8 team members. They work together on the features of our customizable product bundle. You can start with any specialization, but we expect you will grow to be a full-stack developer able to deliver any work fragment. This happens organically, as a result of iterative development, the variability of tasks and team self-organization. Thanks to Quality Assurance, UX, and Product development, you can focus on the areas you know best, and which make you happiest to work on.


Built on a foundation of Open Source projects like CoffeeScript, Node.js, React and Google Closure Tools, we develop one of the most technologically complex solutions on the market. These technologies communicate with scalable data storages like PostgreSQL, HBase and Elasticsearch. We have implemented a Continuous Integration system, so you will know that the code you are working on passed the tests, and, if you break it, that it would be easy to fix. The whole process is implemented on Gitlab and automated tests. Our more than 50 APIs clearly point to our microservices religion. You will learn to love them and write them, too.
