Good software
starts with
good questions.

I’m Rasmus, a software consultant and developer with 15+ years of turning complex challenges into things people can actually use.

From Copenhagen to Barcelona, my approach has stayed the same: understand the problem, question the obvious, and build with care. Today, I run Clovr Labs and explore what’s possible with AI and agentic systems.
