AI Solutions Architect · Developer tooling & process engineering

I architect AI systems, ship them, and build the tooling that proves they work.

I design the architecture, set the constraints and own the release gate; AI coding agents build inside them, under a governance framework I designed. Since March 2026 that has produced 17 applications, 11 of them live, released or in regular use. Four of them are below.

Every number on this site came from the code: measured on from committed source, git history, or a command run that day. How it was measured →

Live captions from a soundboard feed to every phone on the local Wi-Fi, served by one ordinary PC: no cloud, no app. Translation, opt-in, runs on a model that covers about 200 languages. Its speech and translation models were both chosen on measurement.

The Good Soil UMC site opened to its first spread: service times, address and phone on the left; on the right, Find your way, with three drawn pictures labelled To Know, To Grow and To Sow. Tabs run down the right edge.

Good Soil UMC

Fictional church · private source

A website engine for small congregations: the site is a book with tabs, every page a real address, and a help desk that answers from a list the church writes, with no language model. This demo church, all 80 pages of it, was built in a day.

Dev tooling & process

How I build

The agents work under a governance framework I designed: one gated verb, autonomy that changes with whether I’m at the keyboard, rulings you can look up by ID, and a hook that refuses private material before it reaches a public repo or a deploy. Most of it is advisory; the hook and the structure are what actually stop things.
