Patrick Stählin, 29, lives and works in Zurich. After an apprenticeship in application development he attended the University of Applied Sciences in Winterthur (ZHAW) to receive an engineering degree in information technology. He currently works at a Swiss based start-up in Zurich.

In 2005 he registered with OpenStreetMap, which resulted in a very low and very cool OSM user-id, but didn’t start mapping until 2008. The old-town of Zurich is where he’s currently investing most of his scarce mapping resources.
