„I learned in a digital agency, worked in a start-up and grew up in a large publishing house. Now I help others with my knowledge and experiences as a freelancer.“

I create beautiful interfaces and take care about implementation.

I help you to digital success and develop digital platforms with the focus on the user. Together we find out what they want, define problems and make demands. As interaction designer I accompany you through all project phases and make sure that the design works from start to finish.

Surely you often know the problem that you get pretty screens that never look the way you thought after the technical development. In me you will find someone who combines both worlds - visual design and development. In the conception phase I bring in impulses, create a functional design in Figma and then implement it in React or another library - I have been doing this for over nine years.

That's why I'm also the ideal addition to a team of application developers. After the design, I make sure that the body and the engine fit together perfectly.


I'm part of your team

I can integrate myself very well into existing teams and am a good listener to work in a solution-oriented way. I make sure that a functional and good design is created throughout all project phases. Due to my previous experience I know how to work within a remote team.
