# Aaron Roy

> Product leader and builder based in Brooklyn, NY. I write about product management, building with AI (Claude Code, MCP servers, prompt engineering), side projects, 3D printing, cycling, and startups. Currently Product Director at Manychat and co-founder of Wami.

I'm a product person by trade — not an engineer, but increasingly technical through AI tooling. I tend to build something and then write about what I learned: how it works, what it cost, what broke, and what I'd do differently. This site collects that writing.
