I’ve been an OpenStreetMap developer since 2011, and am currently a maintainer of OpenStreetMap Carto, osm2pgsql, as well as various pieces of software I’m the author of.
I’m living in the Seattle, Washington area, but regularly travel between there and Vancouver, BC.
Work
I’m working at Amazon developing map-related software. I used to do freelance consulting work but don’t have the free time anymore. My views are my own, and not those of any current, past, or future employers or clients.
OSMF activities
I’m a member of the Operations Working Group.
If you have a public issue for the Operations Working Group, please create a ticket on our issue tracker, or if the issue is private, contact operations@osmfoundation.org.
At various times I used to be a member of the Data Working Group, Licence Working Group, Engineering Working Group, Membership Working Group, and OSMF Board.
Other accounts
My other accounts are pnorman_imports, pnorman_mechanical and pnorman redaction revert. Doing Data Working Group activities gives me a need to separate out the work more so than most mappers.
