About

Full-stack engineer who pairs production React/TypeScript front-ends with Python AI services in real shipping products. Two years freelancing 20+ LLM-powered apps for paying clients on Claude, OpenAI and LangChain. MSc Advanced Data Science & AI at the University of Liverpool.

I write code that other people maintain, document the workflows so non-engineers can run them, and use AI tooling daily as part of the work rather than as a side project.
