Entrepreneur (Firebase), angel investor (many), international developer (mostly Haiti), and gymnast. Together with James, I’ve started several startups. By far the most successful one was Firebase, which we started in 2011. We sold the company to Google in 2014, where we continued to work and grow the business. Firebase is now by far the largest platform for mobile and web app development in the world. It’s used by ~15% of all developers (rivaling iOS in terms of developer usage, as a comparison).
