About me

My name is Sebastian and I’m a UX/UI designer and freelance artist with roots in Magdeburg, where I was born in 1982. After completing my Industrial Design studies there, I began my career as an Industrial and UI Designer at UID in Ludwigsburg. During that time, I worked on over 30 projects across various industries, including medical, enterprise, industrial, consumer and automotive.

In 2012, I moved to Berlin and joined Useeds (now Diffferent), where I worked as a UI Designer for clients such as Mobile.de, Cortal Consors and BNP Paribas Cardif. In 2014, I took the opportunity to further develop professionally and transitioned into UX design by joining Wooga, a company well known for its casual mobile games. It felt like coming full circle—I was back to creating concepts, just like I had done during my industrial design studies in Magdeburg. As a UX Designer, I was responsible for the entire UX process, including research, interaction design, visual design, prototyping and testing.

In the years that followed, I deepened and expanded my expertise in UX design, continuously developing my skills in shaping digital solutions while working as a Senior UX Designer at Caresyntax, IBM iX, and Verivox, where I led UX design projects and mentored junior designers. In September 2025 I joined Idana AG as a product designer.

As a freelance artist I have participated in various exhibitions and art events.
