About

I work as Director Technology & Product on FYEO for ProSiebenSat.1 Media SE and am located in Cologne, Germany.
Agile development and Scrum have influenced my work since 2012. I have more than ten years of experience in developing scalable web-applications using cutting edge technologies including modern JavaScript and TypeScript (front-end and backend).
I love creating solid systems in a high-performance environment.

My passion for JavaScript and CSS is as strong as my belief in agile methodologies, especially Scrum. Building teams and enabling co-workers to excellerate is what drives my daily work.

Work

In the past I worked on projects for a lot of different clients. You can find more about my list of clients on my portfolio.
