About me

I've been doing backend for 10+ years: payments at Wellhub, two-factor authentication for Santander, and now the Erlang servers behind 8 Ball Pool at Miniclip. I'm happiest working on the parts nobody sees, as long as they never break.

These days I'm having a lot of fun with AI agent workflows in Claude Code. Rotom MCP, for example, lets Claude look up real Pokémon card prices instead of guessing them. I studied Systems Analysis, then Game Development and Game Design, plus an AI bootcamp more recently, which explains why so many of my side projects end up as games.
