About

I am a Software Architect and Certified Scrum Master located in Cologne, Germany. Agile development and Scrum influence my daily 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 (frontend and backend).

I love architecting systems in a high-performance environment with a focus on frontend development. My passion in JavaScript and CSS is as strong as my believe in agile methodologies, especially Scrum.
