I'm best known for building the Napster backend software including real-time search and chat and scaling it up to 80 million users.
I've founded multiple companies. My last one was SNOCAP. It was a real-time copyright clearinghouse that allowed P2P systems to identify content, retrieve licensing information for it and make payments. SNOCAP became the primary MySpace storefront for music.
At heart I'm a problem solver and strive to improve things around me. I've managed engineering teams, implemented agile project management, worked in product development and operations.
I enjoy building companies that I can be passionate about and I make it a point to pick up whatever slack exists. That has led me to being very well rounded. I have experience in all aspects of business, product and technology development.
