A Chrome extension that scores job listings against a resume, tailors resume bullets to the role, and runs a self-critique pass to flag overclaiming in its own output. Built on the Anthropic API.

A metacognition trainer. Predict how much you'll recall, retrieve it from memory, then grade strictly against the reference. A dual-needle gauge reads predicted against actual, and reviews are spaced with a penalty for overconfidence.

A full-stack fitness tracking PWA. Logs workouts, cardio, nutrition, and bodyweight. The production app runs on Supabase auth and PostgreSQL; the demo runs entirely in the browser with seeded sample data.

A browser-based aviation radio communication trainer. Uses the Web Speech API to capture and score spoken readbacks against ATC transmissions. 15-level progression from single words to full clearances.
