About Team

Tomek Chmielewski - Python PM

How do we work?

Currently, we are organized into two teams: one Feature Development Team, which focuses on developing new features and one Maintenance Team, which provides additional tools and optimizes already-implemented solutions. We’re mostly generalists, but team members are semi-specialized in their domains. We do unit tests, functional tests, and “blackbox” testing, using the py.test (with Selenium) and Mocha testing frameworks. Feature Development Team works in Scrums, while the Maintenance Team works in Kanban. Roles within the teams include: Developer, DevOps, Project Manager and Tech Lead.

What makes us special?

We are developing one of the most challenging project in Wrocław (seriously!) and we love to celebrate achieving our sprint goals with cakes!

We welcome people who:

  • Think both logically and outside the box
  • Are creative
  • Are not afraid of being confronted with a variety of problems and opinions
  • Are able to effectively manage their time

We mostly use:
