Tom specializes in building interactive and creative open source mapping tools for Development Seed. He is a lead architect of our open source mapping stack, including the TileMill project that combines Mapnik, Carto, Modest Maps, and other open source tools for use designing custom maps online. He's also the lead developer behind TileLive.js, a dynamic tile rendering toolset that provides fast, non-Flash interactive maps, and the Wax collection of map utilities.

Tom works closely with the rest of the mapping team on the development of MapBox products, a suite of open source tools that make beautiful custom maps and host them in the cloud.

Tom is a frequent speaker on open source mapping technologies, having presented at the International Conference on Crisis Mapping, GOSCON, Where 2.0, FOSS4G, and OpenStreetMap's State of the Map conferences. He recently participated in the first ever code sprint for Mapnik in London.

In addition to mapping, Tom is an experienced open source developer with significant experience working in JavaScript, Node.js, Drupal, Django, and Ruby. He received a bachelor’s degree in computer science from The College of William and Mary.
