Work

I’m a freelance JavaScript developer with 12+ years of professional experience. I work both on the front-end and back-end and although my specialism lies with JavaScript, I have a fair share of knowledge about other things, helping me bridge the gap in a multidisciplinary team.

Recently, I’ve worked with:

JavaScript  TypeScript  Svelte  SvelteKit  React  React Native  Next.js  Jest  Node.js  PostgreSQL  AWS
