Full Stack Engineer based in Norwich, UK. I build products end to end, from the PostgreSQL schema through the TypeScript API to a polished React UI, and I work hands-on with agentic AI.

Right now I'm the primary architect of a greenfield Next.js client portal at TaxAssist, a UK accountancy network with 300+ offices. Before that I spent two years on a cybersecurity team at Darktrace, and delivered client projects at an agency.
