Independence, Missouri

I build software for towns, families, and the people who show up when things go wrong.

I'm a firefighter who ships production software — native apps, civic systems, encrypted infrastructure, and developer tooling. Most of it exists because my family, my department, or my town needed it to.

Lately that work has been about how coding agents find what matters. My retrieval tool prepass placed first of eight on an independent benchmark, ahead of embedding models many times its size — and I built the evaluation that proves it as carefully as I built the tool.

About

A firefighter who ships production software.

I'm an active firefighter with the Sugar Creek Fire Department and a father. That shows up in what I build: family safety, emergency tooling, privacy-first architecture, and software that has to hold up when it matters.

It started in October 2025 at the kitchen table with one question — what can we actually afford? That became an App Store budgeting app, then a render studio with its own Metal engine, open-source tooling on PyPI, a civic reporting platform, and a neighborhood marketplace for my own town. KCTV5 and Fox4 ran segments on GoKC ahead of the 2026 World Cup.

I work nights and after shifts. Every product here was architected and built by me, solo and end to end — the schema, the backend, the interface, the store listing, and the support email.
