David Heinemeier Hansson (born 15 October 1979 in Copenhagen, Denmark; known to the Ruby and ALMS communities as DHH) is a Danish programmer and the creator of the popular Ruby on Rails web development framework and the Instiki wiki. He is also a partner at the web-based software development firm 37signals.
In 1999, Hansson founded and built a Danish online gaming news website and community called Daily Rush, which he ran until 2001.
After attracting the attention of Jason Fried by offering him help with PHP coding, Hansson was hired by Fried to build a web-based project management tool, which ultimately became 37signals' Basecamp software as a service product.
To aid the development process, Hansson used the then-obscure Ruby programming language to develop a custom web framework. The web framework he created was later released separately from the project management tool as the open source project Ruby on Rails. In 2005 he was recognized by Google and O'Reilly with the Hacker of the Year award for his creation of Ruby on Rails.
After graduating from the Copenhagen Business School and receiving his bachelor's degree in Computer Science and Business Administration, he moved from Denmark to Chicago, Illinois, U.S. in November 2005.
Hansson appeared on the cover of the July 2006 issue of Linux Journal which included an interview with him in the feature story 'Opinions on Opinionated Software'. In the same month, the now defunct Business 2.0 web magazine ranked him 34th among "50 people who matter now".
Hansson is an outspoken character known for the crude and brutal way he expresses his opinions, both online and in real life. Hansson and his company have been accused of arrogance, which he does not deny. Hansson is critical of enterprise software saying it is "not about technology or best practices". He created the web-development framework Ruby on Rails to free programmers from what he saw as repetitive coding inherent in platforms such as Java. 
Hansson has expressed the view that women's low participation is not a result of what he called the "testosterone-powered alpha nature" of the programming world. The debate stemmed from a presentation made by a speaker at GoGaRuCo (the Golden Gate Ruby Conference) that included sexually suggestive slides. Hansson has received criticism for his endorsement of behavior seen as radical and crude.

"Rails developer David Heinemeier Hansson posted to Twitter, “I’d much rather we went with beautiful women for the filler stock art. Works in ads.” Heinemeier Hansson doesn’t seem to understand that very few people are likely to feel comfortable in a community where they are only expected to play the role of human advertising material. The insensitivity that Ruby VIPs demonstrate in the face of numerous, anonymous comments online helps illustrate one of the major reasons for the marginal participation of women at open source community events."
