Hi there! I’m a Web developer and musician in Chicago.


I'm currently building Soundslice, quite possibly the best guitar tablature software ever!

It does a ton of fancy HTML5 stuff, and you can find out more by watching this talk I gave at 37signals.


I founded EveryBlock, a neighborhood news and discussion site, in 2007. It was sold to in 2009. I worked there until mid-2012. Unfortunately was later bought by NBC News, which decided to shut it down in early 2013.

I’m co-creator and co-Benevolent Dictator For Life of the open-source Django Web framework, which is used by tens of thousands of people around the world!

My 2005 site (now superceded by EveryBlock) was one of the original Google Maps mashups and influenced a bunch of stuff. It played a small part in influencing Google to release a mapping API; the New York Times named it one of the year's best ideas; it inspired the creation of the Mashable blog. Most importantly, it helped a lot of Chicagoans get a sense of neighborhood crime.
