Five things I've designed and shipped.

Each one is real, and each is its own world. Scroll to step into them, one at a time.

Lab Logger

Describe an experiment in plain language. It writes the work up, organizes it, and remembers it, so the lab notebook finally keeps up with the bench.

About

A nurse who builds the software he wished he'd had on shift.

I spent years at the bedside before I wrote a line of production code. That order is the point. I build for the people using clinical software under pressure, not for the spec.

I design for the person holding the chart at 3am, not the person reading the requirements doc.

BEDSIDE

I started as a nurse

Clinical shifts across four systems (City of Hope, CHLA, Kaiser, and SAHZU) taught me how software actually meets human stakes, and how rarely it's built for the person holding the chart at 3am.

CROSSOVER

I taught myself to build

I learned to design and ship software to fix the tools I wished I'd had on shift. Lab Logger was the first, built from the gap between charting a result and understanding it.

NOW

I build from inside care

Finishing a BSN while shipping healthcare and AI products. The bedside isn't a market I researched. It's where I came from, and it's the through-line in everything here.
