Don't hesitate to contact me if you want to see my current portfolio & CV via E-Mail.

How I work

My passion is UI design: Working on the screen layouts & concepts, designing interaction elements, creating UI components, developing design languages & systems.

Since I see myself as a link between UX and development I like working very close together with the product team, UX designers and developers. The perfect working condition for me is the combination of remote + inhouse at companies as part of agile teams.

Alter egos

As a trainer I’m now proud part of the Cologne based Experience Design Institute XDi and teach people to become Mobile UX & UI Design Specialists or Digital Designer.

Sometimes I write and highlight articles on medium.com.

Hire me

Well, that's it for now. If you think I'd be a good fit for your team, let's work together.
You can hire me as a team or independently.
