I am a computer scientist, but not very active in programming anymore because 10+ years ago I switched to consulting. I own the company Scrum-Master.de and am a coach for agile and lean (multi) project management with frameworks like Scrum, Kanban, Theory of Constraints etc.

My main occupation is management consulting, training and coaching on the job for project managers and teams.

My hobby is Freetz, an embedded firmware modification for DSL/LAN/WiFi routers by German producer AVM (Fritz!Box series plus OEM versions like T-Com Speedport). [Update: I left the project in 2012.]
