Mapper since: January 26, 2008
OSM is a great platform for citizen mapping and making visible those things that don’t make it onto official maps. I maintain an active interest in improving addresses and addressing in OSM. I also have a great interest in developing and diversifying the OSM community, particularly students & young users.
I’m active mostly in the Washington, DC area, particularly Arlington, VA, but often make contributions as I travel. I am a frequent contributor and participant in MappingDC activities.
