Scottish builder, just landed in the US. I make apps and products end-to-end — three trading card games at 700K+ downloads, an AI voice-agent platform, and a family-organizer app, all shipped solo. Looking for a founding engineer role.

Sincerely the best shoe game I've ever played — and when I say that, I MEAN that.

★★★★★
The cards themselves are great. You get the full name of the shoe and the real-life price, which I think is cool.

★★★★★
The mini games are perfectly varied — there's one for every kind of fan, from casual to sneaker aficionado.

One of the best apps I've downloaded in recent memory. So fun to collect my favourite movies, and some of the best movie trivia around.

Without a shadow of doubt, it's the best music collecting game OAT.

Way more addicting than I expected. If you're into trading card games and music, this is right up your alley.

I've been using this app to stay on top of all the family stuff and it's honestly been a lifesaver.

The grocery list and to-do list features make organizing so easy.

Year one

Boxed Up was growing by five to ten users a day from paid ads. I built a Discord and pushed players to it — about twenty joined. Then one of them crossposted us into the server of a similar game.

Went to sleep with 20 in the Discord. Woke up with 120.

The night Boxed Up's growth started
II. Still shipping

Boxed Up still grows.

year four, still profitable

Year four

The codebase had calcified, features were piling up faster than I could ship them. So I rebuilt the app from the ground up — on a stack designed around what an AI coding agent does well.

I stopped treating AI as a force multiplier and started treating it as a teammate.

On the 2026 rebuild
III. What's next

Four years solo.

Now I want a team.

the right product, the right people
