DAVID HEINEMEIER HANSSON is the cofounder of Basecamp and the New York Times bestselling coauthor of REWORK and REMOTE. He's also the creator of the software toolkit Ruby on Rails, which has been used to launch and power Twitter, Shopify, GitHub, Airbnb, Square, and over a million other web applications. Originally from Denmark, he moved to Chicago in 2005 and now divides his time between the US and Spain with his wife and two sons. In his spare time, he enjoys 200-mph race cars in international competition, taking cliché pictures of sunsets and kids, and ranting far too much on Twitter.
