      In my role as a team lead I got interested in leading people through the coaching program of relaxdays. And as my team was very successful I got the chance to inspire other development teams. I am currently managing 2 teams and am also acting as an interim Product Owner for my old team.

    • IT-Teamleiter
      Mar 2021 - Feb 2022 · 1 yr

      I had the chance to build my first team and over the course of nearly one year grew it to 7 people. We built a PWA for internal use, that allowed users to manage prices for over 20.000 articles. For that purpose we also built a C# GraphQL backend, that allowed us to decouple our frontend and backend tasks a bit more and we were able to deliver many features because of that. I helped organizing the first hackathons relaxdays did, by creating tasks and evaluating submissions. Also I got to mentor three wonderful working students with their theses.
