Senior Frontend Engineer in London with 7+ years building React/TypeScript applications across regulated SaaS, fintech, and e-commerce. I build Next.js/Remix server routes and Node BFFs to handle auth and data shaping so the client stays simple. Day to day I ship micro-frontends, own shared UI libraries, and focus on performance, testing, and safe releases.

Most of my commercial work is private (NDA), but I'm happy to talk about approach, architecture, and outcomes.

I lead small teams, write RFCs, mentor engineers, and work closely with product stakeholders and design teams from discovery to release.
