I'm currently working on Tonic, a new and improved REPL for Node.js.

I helped create Cappuccino, the best way to create interactive applications that run on the web.

I founded 280 North with my friends Francisco Tolmasky and Tom Robinson. We made 280 Slides and Atlas.

I designed and built many things at Stripe.

I write code and contribute to open source on Github.

I sometimes have vaguely interesting things to say on Twitter.

I can be reached via e-mail.
