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
