From OSGeo Wiki
I am a GIS developer, using open source software for developing web mapping applications and analysis, and interested in improving open source tools as I can and time permits.
My main projects include OpenStreetMap, which I work on in the Washington DC area with the MappingDC group. We organize mapping parties, are working on data imports for DC, and outreach to other local governments.
I am also involved with Wikimedia projects and MediaWiki development.
