Parker Fawcett

I'm Parker. I work on AI systems and the tooling around them, plus a few small products. Most of my time right now is on evaluation, how you tell whether an AI system actually does what you claim, and on open source infrastructure that makes that check reproducible.

Featured work

Rebuild-Dossier: https://github.com/Parker-Fawcett/rebuild-dossier A tool that reverse engineers a rebuild spec from a running app. It generates a locked CLAUDE.md and tests you can run to see if a rebuild matches the original. Paper: https://arxiv.org/abs/2608.23616 | DOI: https://doi.org/10.5281/zenodo.22036801

CatchAndTrade: https://github.com/Parker-Fawcett/catchandtrade (live at https://catchandtrade.com) Trading card marketplace and portfolio. Full stack, TypeScript monorepo.

Totally-Normal: https://github.com/Parker-Fawcett/Totally-Normal A site built entirely in Whitespace. The source file has no visible characters.

How I build

Mostly Python and TypeScript. React and Next.js on the front end, Postgres and Docker underneath. I've also used Kotlin and JavaScript a lot.
