Hi, I’m Tom.

Right now I’m building Val.town, a tool for joyful programming, and working on Placemark, a tool for creating maps.

In 2020, I was working on a “stealth startup” in the intersection of hardware and software. From 2017 to 2019, I helped build, design, and grow Observable as the first hire. Before that, from 2009 to 2017, I helped build Mapbox, a company that makes mapping software. I played in a band that released three albums, rallied for open laws and succeeded, wrote code for understanding and interacting with statistics, sleep, the earth, open data, manners, music, and a bunch of other stuff.

For a while, I was involved in the d3 community and the OpenStreetMap community: I was a lead developer on the editor you probably use if you edit OpenStreetMap. I made geojson.io and Mapbox Studio, and helped with Mapbox GL JS and a lot of other stuff.

To keep updated with my work, follow me on Twitter, Mastodon, or GitHub or subscribe to this blog with RSS or Feedly.
