Jeff has a long history of early technology adoption. After helping to launch CNN.com on the Internet in the early 1990s, he worked for many successful Internet startups and service providers. Concurrently, he worked continuously on open source software engineering projects for over two decades. His involvement in one of the best known open source projects — the Linux kernel — led to an extended tenure at Linux market leader Red Hat during open source's most formative years. Jeff's work is found in every Android phone and data center running Linux today.
In July 2010, Jeff came across a post describing bitcoin. Recognizing the potential of a concept previously thought impossible — decentralized digital money — he began contributing to Bitcoin’s open source software as a developer. He was one of the first Bitcoin developers. Jeff found himself at the heart of the global, revolutionary, technology phenomenon known as bitcoin.
