I am an all-year bicyclist who works as a software developer. I got my first GPS receiver in January 2009, a Garmin Edge 705 that I power from my self-made USB dynamo charger. I have contributed minor fixes to JOSM. I am mapping mostly passively (carrying the GPS with me when I go to new places). I provide a map of Finland in Garmin format and maintain the Mkgmap default style. I routinely fix mapping errors in Finland.
In 2012, I switched to using OsmAnd on a SonyEricsson Xperia Active.
