What I'm looking for

Actively looking and available immediately. Seeking Frontend Engineer roles (React, Next.js, React Native, TypeScript), remote or hybrid in Germany and the EU, with product teams that value performance, quality and ownership.

I’m building a production website for a used-car dealership in Germany, using Next.js, TypeScript, PostgreSQL, and Drizzle ORM. I also engineered an automated mobile.de listings sync and lead forms that work without JavaScript.

At Lunka Tech, I architected a real-time event booking system for 10,000+ users and developed payment flows that processed 1,000+ transactions across three production apps. At Everridge, I built offline-first sync for a field logistics application and integrated geolocation and mapping for routes across 150+ retail outlets.
