Description

Frontend developer based in Berlin with 2 years of professional experience building web applications end-to-end. Currently working full-time at Nosto Solutions, I take on freelance projects on the side for teams who need clean, production-ready frontend work.

I work primarily with React, Vue, and SvelteKit using TypeScript. I'm comfortable handling the full picture: UI, backend integrations, databases, auth, and deployment on Vercel or Firebase.

Recent projects include a full-stack e-commerce platform built with SvelteKit, TypeScript, PostgreSQL and Drizzle, and a live artist portfolio site built for a client using Vue and Firebase.

I'm available for project-based work and short missions. I work in English, fully remote in Berlin.
