AI Product Engineer — I ship real software with AI in the loop, in the open.

I work where product, engineering, and AI systems meet: AI-assisted delivery, AI agents, automation, developer tooling, testing and evaluation, and the architecture that holds it all together.

• 🛠️ Building useful open-source tools.
• 🤖 AI-assisted engineering — and being honest that it's part of how I work.
• ✍️ Writing clearly about how the work actually gets done.
• 🔒 Security research and responsible disclosure.

• overkill — OVERKILL: Claude Opus 5.5 overengineers chores as chain-reaction machines; a deterministic physics sim, not the model, decides whether each one works. Live: overkill-95w.pages.dev (machines designed offline; live generation needs an API key and isn't running). Prove.
• delivery-gate (source private) — a CLI that gives a hard GO/NO-GO on a release: machine auto-checks plus a human-attested manifest. Enforce.
• hallucination-hunter — detect & score LLM hallucinations by groundedness; runs offline, no API key. Measure.
• ai-delivery-engineering — a playbook for shipping software reliably with AI-assisted workflows. Methodology.
• field-lab — the portfolio hub, live at field-lab.pages.dev.
• CONTROL ROOM (source private) — directs AI coding agents through a visible Scout → Builder → Verifier chain, gated by human approval at every step. Live demo: control-room-build-week-2026.pages.dev. Submitted to OpenAI Build Week 2026, Education track. Supervise.

Ten languages, ten small apps — one small browser app per language, each one live, each README with its tests and limits.

• overprint (live) · Rust → WASM — a photo becomes a two-ink riso print. Print.
• sky-report (live) · GLSL + TypeScript + Pages Function — the live sky, ray-marched from an airport's current METAR. Render.
• small-print (live) · Python in the browser (Pyodide) — any Terms of Service mapped clause by clause by 53 hand-written rules, every quote verified; free, no AI, nothing leaves your device. Verify.
• silt (live) · Zig → WASM — 10,000 years of rain carving a painted mountain. Simulate.
• tide-table (live) · Go → WASM — a cron schedule as a year-long almanac, daylight-saving seams included. Schedule.
• paren (live) · ClojureScript — a Lisp expression evaluated one substitution at a time. Step.
• single-track (live) · Elm — a single-track timetable puzzle, par proven on plates I–VIII. Solve.
• sideband (live) · C → WASM, AudioWorklet — a six-operator FM synth in the audio thread. Play.
• knot (live) · TypeScript + Three.js — draw a rope in 3D; it works out which knot you tied. Identify.
• stroke-order (live) · Kotlin/JS — write a kanji; order and direction checked stroke by stroke. Write.

Built with AI-assisted engineering. The work is real; the method is part of the point.
