EveryBlock 🔗

I co-founded EveryBlock with Adrian Holovaty, Wilson Miner, and Dan X. O’Neil in 2007 in Chicago.

I developed the site along with Adrian, writing Python code for the Django-based application, administering the PostgreSQL/PostGIS database, writing JavaScript for various front-end elements including our OpenLayers-based custom maps. We were early users of Mapnik, which we used to create the map tiles. I also developed a custom nginx module to efficiently serve the tiles. I wrote an article about our maps.
