👋 Hi, my name is William! I'm a Product Engineer on the Applied AI team at Anthropic, where I partner with our early-stage startup customers.
Before Anthropic, I founded RiskAngle, an AI platform to summarize medical records for law firms. I closed our first clients, built the product end-to-end, and got funded by Y Combinator.
In my free time, I enjoy playing volleyball, watching anime, and solving crossword puzzles. If you're interested in connecting, please reach out via LinkedIn or email.
