I came to Karlsruhe for my studies, started working at synyx and stayed here after switching to working as an independent developer and consultant. For years I helped running the local Java User Group, I am one of the founders of the Search Meetup Karlsruhe and most of my clients are from the area as well. Though my wife and myself liked it here we decided it's time for a change: We'll be relocating to Singapore for at least a year.
