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.
- delivery-gate — 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.
- openai-build-week-2026 — CONTROL ROOM: 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 README with its tests and limits.
- overprint · Rust → WASM — a photo becomes a two-ink riso print. Print.
- sky-report · GLSL + TypeScript + Worker — the live sky, ray-marched from an airport's METAR. Render.
- small-print · Python Worker — Terms of Service mapped clause by clause, every quote verified. Verify.
- silt · Zig → WASM — 10,000 years of rain carving a painted mountain. Simulate.
- tide-table · Go → WASM — a cron schedule as a year-long almanac, daylight-saving seams included. Schedule.
- paren · ClojureScript — a Lisp expression evaluated one substitution at a time. Step.
- single-track · Elm — a single-track timetable puzzle, par proven on plates I–VIII. Solve.
- sideband · C → WASM, AudioWorklet — a six-operator FM synth in the audio thread. Play.
- knot · TypeScript + Three.js — draw a rope in 3D; it works out which knot you tied. Identify.
- stroke-order · Kotlin/JS — write a kanji; order and direction checked stroke by stroke. Write.
