Originally from Wisconsin, he freelanced his way through high school and college before dropping out and moving to California to work at a design firm, ZURB, in 2007. There he designed and developed dozens of projects with clients large and small, including a website for Britney Spears. In early 2010, after a two-and-a-half year stint at ZURB, he left to become a product designer at Twitter. At Twitter, he worked on numerous projects including the Promoted Products campaign tools and badges, during #NewNewTwitter, the Twitter Help Center, and several internal tools.
