Hi! I'm Johannes

Web & Android App Developer
Based in Stockholm, specializing in modern web technologies and mobile app development.

About Me

I am a passion-driven developer focused on building scalable, performant, and beautiful user experiences across Web and Mobile. I bridge the gap between robust frontend logic and clean UI/UX design.

  • Current Focus: Deep diving into native Android development with Jetpack Compose & Cloud integration.
  • Efficiency workflow: I leverage modern AI tools (Lovable, Claude, Copilot) to rapidly prototype UI/UX ideas and accelerate development cycles without compromising on clean code architecture.
  • Fun fact: I’ve spent more time centering divs than I’m willing to admit.
