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.
In my daytime job I do management consulting, training and coaching on the job for project managers and teams.
My main area of interest here on StackOverflow is AspectJ. I am kind of an expert on this subject matter and like to answer related questions. Sometimes I also answer plain Java questions.
