Things I build with AI outside the day job — a way to stay close to the
craft while running an engineering org.
Ferry Tracker
2025 Real-time tracker for Washington State Ferries on iOS, Android, and web. Live vessel positions, upcoming departures, and drive-up space availability, plus personalized “leave by” times from a trimmed-mean model over your own recorded crossings. Serverless AWS CDK backend on the WSDOT ferry APIs.
Family Retreat Booking
2023 — Present Full-stack app where an extended family reserves days at a shared vacation home — with a booking-approval workflow, shared task tracking, local weather and tides, photo sharing, and an AI chat assistant. Built hands-on across the AWS stack (Cognito, Lambda, DynamoDB, API Gateway, SES, Bedrock, S3, CloudFront) behind a cross-platform React Native front end.
Birthday App
2025 A custom cross-platform app built as a personal birthday gift — an animated card with ASCII art, confetti cannons, balloons, and interactive fireworks, bundled with a few homemade mini-games (basketball, Snake, and a Wordle clone).
Turntable Speed
2025 Point a phone camera at a spinning record and it measures the turntable's true speed and wow-and-flutter in real time — tracking the label's rotation frame-by-frame through an FFT and phase-correlation pipeline, no test record or strobe disc required. The signal-processing core is dependency-free and unit-tested.
