Full Stack Developer in Hanover, Germany, He/him


I am a developer and designer from Germany. Focused on creating consistent and clear design languages for rich, beautiful products.

Full Stack Developer at neuwaerts, Co-Founder of XVI CHAPEL, Marketing Manager at World of Bass and Freelance Designer & Developer - over the past decade I have had the delight of experiencing many facets of the design industry.

Today I work at neuwaerts. I consult clients, design and develop their products, and deploy them. In my spare time I contribute to aggregata.de and freelance for selected clients.
