Summary

I am Jonas and I work as a freelance Product Owner for web, API, backend, and app development teams.

I work best in a team with talented designers and developers. I act as a multiplier who makes sure every person has all the necessary information and can work at their best.

My technical and analytical skills ensure well-thought-out concepts and efficient refinements.

With my understanding of both worlds, I build a bridge between business and IT.
