Builder of AI-powered tools · operations leader

I build working software end to end — I find the problem, set the rules for what “correct” means, direct AI coding tools to write the code, and keep testing until it holds up in daily use. Behind that is ten years of running stores and leading teams, so I build for the people who will actually use the tool.

Selected projects

Tessrix · delivery certificate checker

v4.11

Takes a delivery invoice, finds each product’s lab certificate on 15+ differently built vendor sites, reads every PDF, checks the numbers and dates against Arizona’s rules, and exports a file ready for a point-of-sale import.

Atelier · home dashboard

In daily use

The family’s front page on my PC: a living sky, dinner, calendars and chores, and a voice assistant you can talk to. Built by directing AI coding agents under a verify-everything process.

Live · gilding.app

One line in, a finished scene out: Claude expands a sketch into an art director’s brief, an image model renders it, and it hangs in a private gallery to post or remix.
