A bit about me

I build the parts of software you don't see: APIs, data pipelines, deployment and the analysis behind the numbers.

I’m a student at King’s College London who likes maths, computer science and the places where they meet real systems. I’m happiest working on the backend: designing the data model, writing the service, getting it deployed and making it fast enough that nobody notices it’s there.

Before university I studied Mathematics, Further Mathematics, Computer Science and Physics. I started programming by writing Minecraft server plugins and Discord bots in Java and Python, which taught me early that other people will use what you ship in ways you never planned for.

Lately I’ve been working on data and analysis. At OxHack 2026 I built the backend for Eisengrau, running forecast backtests and statistical tests over Great Britain’s electricity market, and shipping it to a VPS with CI/CD during the 25-hour build window.

Away from the keyboard, I DJ.
