Rails
David Heinemeier Hansson

David is the creator and lead developer on Rails. He laid the first tracks for Rails working in PHP, but only after running into Ruby did he decide to contemplate a public release.

David has used Rails to build Basecamp—a web-based project management designed by the experts from 37signals. Actually, it could just as well be said that he used Basecamp to build Rails. Or that the two build eachother.
