I take ideas all the way through: deciding what’s worth making, designing it, building it across the stack, and improving it after it ships.

A clearer view of what moving could cost.
A rental calculator for London, Basel, and Zurich. It brings salary, moving costs, and local assumptions together so you can work out what a move might take.
02 · Event-driven systems
A local simulator for a multi-currency risk platform. Follow simulated prices and trades through the system and into portfolio calculations.

A focus timer that keeps accurate time when its browser tab is in the background. It saves your history on your device and asks what you want to do if you close the tab mid-session.

03 / About
I studied history at university. Not with a career in mind, just because I loved it, and I still do: the story of how people got from prehistory to now.
After uni I went into marketing. My dad worked in advertising, and I still remember him bringing home doughnuts from a Greggs campaign and telling me all about it. I ended up in digital marketing in healthcare, and the part I enjoyed most was working with the engineers who built our website.
Then a friend who’s a quant researcher told me about a hectic week at work, and I could hear how much he loved it. I wanted that feeling from my own work.
So I started coding in my spare time, no pressure, just to see. I loved it: thinking hard about how to build or fix something, and the fact that if you have an idea, you can just build it.
I went all in: a full-stack role at an e-commerce business, with a software engineering bootcamp alongside it. That led to my role at BNP Paribas, where I’ve been ever since. I still love it as much as I did at the start.
