Co-founder of mySymptoms, a food and symptom diary for people with chronic gut conditions. Thirty-five years building software. Lately I've been building small things with AI coding tools and writing up what happened.
Things I've built
- mySymptoms. A food and symptom diary. Co-founder since 2018.
- YT Music Album Sorter. A Chrome extension that sorts your YouTube Music albums by artist, or into sections you name. Alpha, September 2026.
- Snapity. An app that turns event posters and invitations into calendar entries. Android, iOS and desktop.
Writing
Building Snapity without writing the code
In 2025 I tried to build, publish and market an app with coding agents, without writing a line of code or a word of copy myself.
How much work was left when the agent wrote all the code
An agent wrote all the code for my Chrome extension and I didn't read any of it. Its first version was still a long way from something I'd release.
I wanted the shelf back
Streaming is better than a CD rack in every measurable way, and I stopped browsing music when I moved to it. So I built the shelf.

SRA comprehension cards never told me why an answer was right. ChatGPT argued the point until I understood it.
