Since October 2013 I'm an international FIDE-Arbiter. I was Chief Arbiter of several Elo-rated tournaments, e.g. the German Youth Championship or in the German Bundesliga.
In 2014, with a friend I founded the chess.io UG. It aims to develop web-based applications for chess players, e.g. to manage chess tournaments online. Some of its related projects are listed below.
For the German Chess Youth I have organized tournaments with several hundred players each.
