About

I work on GIS and address infrastructure for the public sector. I'm porting France's Base Adresse Nationale (BAN) to the United States as the National Address Platform (NAP) — a free, open-source, platform-agnostic system so local governments can manage addresses as a critical asset and support NAD, Census, NG911, and statewide programs.

At Fresno County I build tools that connect authoritative data with the open map ecosystem. We were the first public agency to join the Overture Maps Foundation. I maintain an ArcGIS Pro GeoParquet add-in for bringing Overture Maps data into ArcGIS Pro, and I collaborate with the AddressForAll Institute on the NAP project.
