Build log

I still build, and I think anyone selling AI should. These are short, dated notes on what I've made, what it's built with, and what I learned. Client work stays private; this is my own.

This site

georgemckenna.com, built in a day. One place that says who I am and joins up the companies. It's written for people and for AI assistants: every page carries structured data, and there's a plain facts page and an llms.txt.

Stack: Next.js, TypeScript, Tailwind CSS, Vercel

If you sell AI search visibility, your own name had better be findable. Mine wasn't yet.

Skywave

A hobby project to bring amateur radio tools up to date, starting with a live map of FT8 band activity and current band conditions. Built while studying for my Foundation licence.

Hobbies are the best place to try new tools. Nobody's invoice depends on it.

ettgroup.ai homepage

Rebuilt the ETT homepage around three starting points: the board wants AI and the regulator wants proof; whatever gets built, my name's on it; we've run the pilots and nothing has shipped. Made crawlable for AI search from the start.
