I’m speaking this year at [Google I O](http://code.google.com/events/io/speakers.html “Our talk is “AppEngine Nitty Gritty””) in San Francisco.

I’ll be there with my friends Jesse and Josh; we’re going to talk about building highly scalable applications using Google AppEngine and Amazon’s Web Services. Jesse, Josh, and I built the Walk Score API using AppEngine, EC2, and S3. The API gets tens of millions of daily hits from big-name customers like Zillow and Redfin. Best of all, it costs pennies to maintain.

We’re looking forward to meeting you there. We promise fireworks and/or leprechauns at our talk!
