Portfolio

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.

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

Clients

As a freelance designer I work together with others (e.g. tapwork.de, grad7.de) as well as independent for diverse agencies, companies and start-ups. Some happy clients I can drop here are for example:

Workshops

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

In addition, I offer an individually adaptable Sketch – UI Design Workshop, which can take place remotely or in-house, as desired.

Wanna team up?

Cool. Let’s do it and build some beautiful & functional digital products.

You can hire me as a team, independently or for workshops.
