Resume

I'm a freelance software developer building web applications and SaaS products. I also consult on architecture decisions, technical audits, and modernizing legacy systems. In recent years I've worked with Frontnow, Parfümerie Douglas, carauktion and sipgate.

In late 2025 I founded Studio Nordwerk, an AI and software studio focused on pragmatic SaaS solutions and rapid MVPs.
