About Team

Jarek Miazga - Product Manager

How do we work?

The whole team works in one big, spacious room. Each developer chooses their own operating system and IDE – according to his/her preferences. In our projects, we use a methodology based on Scrum - we have chosen the best practices from it and we’ve adopted them to our needs. In principle, depending on the project’s possibilities, the work proceeds in sprints and the project specification is defined by user stories etc. When it comes to developing software, we use workflows based on JIRA and Stash. To manage code versions, we use GIT – gitflow used in software development is based on feature branches and pull requests, which are the subject of code review. We automate deployments with the help of Fabric. We also use tools like Vagrant, Docker and Sentry.

What makes us special?

  • Almost half of our team are cycling enthusiasts and use bikes to get around town
  • Our ritual: every Friday is pizza day

We welcome people who are:

  • Reliable
  • Committed
  • Great communicators

We mostly use:
