David Heinemeier Hansson (DHH) is a Danish programmer, entrepreneur, and racing driver best known for creating Ruby on Rails - the open-source web framework that powered GitHub, Shopify, Airbnb, and thousands of other companies. As CTO and co-owner of 37signals (makers of Basecamp and HEY email), he is one of tech's most outspoken critics of venture capital culture, cloud computing excess, and hustle-culture mythology. A 12-time Le Mans competitor with a class championship in 2014, DHH is also a bestselling author (REWORK, Remote) and a prolific open-source contributor whose side projects routinely reshape developer culture.
