About Me

JRL

I'm a fullstack developer based in Copenhagen, Denmark — currently studying at CPH Business. I'm driven by the intersection of clean code and beautiful design, building products that feel as good as they function.

When I'm not shipping features, you'll find me diving into AI systems, exploring new frameworks, and turning complex problems into elegant solutions.
