David Heinemeier Hansson, also known as DHH, is a talented person from Denmark. He is a programmer, a writer, an entrepreneur (someone who starts businesses), and even a racing driver. He is famous for creating Ruby on Rails, which is a special tool for building websites. He also works as a partner and chief technology officer (CTO) at a software company called 37signals.
David has written several books with his co-author Jason Fried. These books include Getting Real, Rework, Remote, and It Doesn't Have to Be Crazy at Work. He also co-wrote Agile Web Development with Rails with Dave Thomas.

David's Programming Journey
In 1999, David started his own online gaming news website in Denmark called Daily Rush. He managed it until 2001. Later, he helped Jason Fried with some computer coding. Because of this, Jason hired David to create a web-based tool to help people manage their projects. This tool eventually became Basecamp, a popular software product from 37signals.
To build Basecamp, David used a programming language called Ruby. He created a special tool, or "framework," to make the process easier. In 2004, he shared this tool with everyone as an open-source project called Ruby on Rails. This meant other programmers could use and improve it. In 2005, Google and O'Reilly gave him the "Hacker of the Year" award for creating Ruby on Rails. After finishing his studies in Denmark, David moved to Chicago, Illinois, U.S. in November 2005.
