001 / ABOUT

I build things people actually use.

I'm a frontend engineer with 5+ years building scalable React applications for high-traffic platforms. I specialise in component architecture, TypeScript-first development, and shipping features that have real, measurable impact.

At Future Plc I own features from design through to production, and I built the shared component library that became the foundation for frontend work across the whole org. Lately I've gone deep on LLM-enabled product features. One example: orchestrating tool-use APIs with flood and subsidence data to generate on-demand property risk scores for any UK postcode.

My route here wasn't typical. A biology degree, a few years training baristas and coffee teams, then a hard pivot into code during the 2020 lockdowns. The throughline never changed: break messy problems down, and teach myself whatever the next one needs.

Outside of code I embroider, build terrariums, and tend to 40 (and counting) houseplants. Apparently I like nurturing things that take patience and attention to detail.
