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.

The relevant results should all be on the top positions. As the saying goes, if you want to make sure a secret stays a secret put it on page 3 of a Google search result page.
