A bit about me

I'm a data scientist with a passion for building useful things — whether that's a financial model, a geospatial web app, or an LLM-powered tool.

I enjoy the full stack of data work: pulling and cleaning data, exploratory analysis, modelling, and shipping something people can actually use.

Outside of work I like to spend time on projects that scratch a personal itch — finding the best halfway pub being a prime example.
