I've traveled extensively (every continent but Antarctica) and written a book about my adventures thus far.

Here are some of my favorite pictures from the trips:


  • UPenn Wharton'05 cum laude. Concentrations in Entrepreneurship and Information Systems.
  • Oldest of 5 children
  • Avid cyclist (steel, distance)
  • Philosophy: act utilitarianism
  • Funniest thing I have ever seen: a potato I shot 50 yards straight into the air landing squarely on my uncle's upturned face
  • Food: spicy, lots
  • Beer: dark, strong
  • Frequent runner (runnee?) of Puck, my big red dog



With the artistic guidance, mad skillz, and inaccurate measurement of Heather Stewart, we build off-grid, open-source tiny houses out of used shipping containers.
In addition to custom orders, we might have room for you at our extralegal West Oakland colony:)
