01 About

Full-stack, specialised in frontend

I work across the whole stack, but the front end is where I go deepest: component architecture, state management, design systems, accessibility. Years of Angular and Nx monorepos, now building in Vue, and fluent in the layers underneath: Node, NestJS, SQL, serverless AWS. I care about scalable structure and a seamless user experience in equal measure.
