Senior full-stack engineer with 8 years of experience, strongest in React and TypeScript, with production backend work in Python, Go, Elixir, and Node.js. I currently work at Robinhood, and before that at LaunchDarkly, AWS, theScore (ESPN Bet), and Airbnb through Capgemini. I usually own a feature from the interface through the API and the data behind it. I'm looking for senior product engineering work, full-time or contract.

I build retirement and trust features from the Next.js front end through the Python APIs, with service contracts in gRPC and Protocol Buffers. I also built a PySpark pipeline and Superset dashboards for traffic and conversion, and tightened Content Security Policy across the sites.

Built the in-casino sports betting platform at theScore (ESPN Bet) from greenfield to production: self-serve kiosks, an over-the-counter experience, and a back office tool. I designed most of the client architecture and owned the OTC experience, including an Elixir service that keeps the clerk and patron screens on the same live prices.
