(01) — Manifesto

I build products end to end — the interface people touch, and the AI they never see. Designed to disappear. Engineered to last.

(03) — Now

Right now I'm vibecoding full products from scratch — iOS, macOS, web — and wiring the AI inside them: agents and automations that actually run.

End-to-end products

From first flow to shipped — design, front-end, backend and AI, by one person.

AI agents & automation

Put n8n, Hermes and OpenClaw to work — automate the busywork, not the people.

Fractional product design

Embed with your team and move fast — strategy, UX and UI on demand.
