Overcast is an iOS podcast app.

Accidental Tech Podcast is a weekly tech show with my friends Casey Liss and John Siracusa.

Under The Radar is a weekly iOS indie-app-development show with my friend “Underscore” David Smith.

And sometimes I write things on this site.

Past Projects

Tumblr Instapaper The Magazine Build and Analyze podcast Neutral podcast

From its inception in late 2006 through September 2010, I was the lead developer of Tumblr. Here’s some history.

I created Instapaper and ran it for over five years until its sale in April 2013.

I also founded The Magazine in 2012, then sold it in May 2013 to its editor.

Build and Analyze was my podcast with Dan Benjamin, mostly about software development, from 2010–2012.

Neutral was a casual car podcast with Casey Liss and John Siracusa that’s mostly retired now, but accidentally formed our Accidental Tech Podcast in its wake. Occasional car discussions are still tacked onto the after-show segments on ATP.
