Freelance web & tool developer from Germany.
I build local-first desktop apps that respect your privacy and clean, fast
websites for small businesses. Cyan on black, no bloat.
Local-first, privacy-respecting, and shipped — no cloud, no account, no telemetry.

I help small and medium businesses across the DACH region with websites that load fast and look sharp, and I build local-first tools — invoicing, document workflows, domain-specific apps — that keep sensitive data on the user's own machine. Recent client work spans the automotive, agriculture, landscaping and trades sectors.
