Mapper since: December 16, 2007
I enjoy the occasional mapping here in Colorado and use it as an excuse to go out and explore my surrounding and the Rocky Mountains.
Most of my time I have spare to devote to OSM however goes into helping developing parts of the software of OSM. Particularly the map rendering toolchain with osm2pgsql and mod_tile for which I am currently the maintainer.
I started off with OpenStreetMap in 2009, when I was looking for an offline map for my old feature phone, as I kept getting lost while cycling through london, and OSM was the only available option. I used and quickly started developing and improving GpsMid (http://gpsmid.sourceforge.net/) which is a java midlet to get vectorized osm data onto your phone for offline navigation. And I have "stuck" with OpenStreetMap ever since.
I also help maintain the Wikipedia efforts of integrating OpenStreetMap into Wikipedia on the toolserver.
