Design Engineer
I design it, build it and ship it. Today as co-founder and CPO of koorvi, the branded resale platform.
Ten years of products, from AgTech platforms to my own company. Four of them in depth.




Also built: Meine Buchberatung, Mint & Limes, Circular Munich, FindMyself, Carrotinator, How to Boarisch and AutoScout24.
In-house, as a freelancer and as a co-founder.
Three ways I help teams move from idea to shipped product.
Research, interaction and visual design that make a product feel obvious, on a design system that grows with the team.
Deciding what to build and what to leave out. Discovery, clear priorities and metrics that show whether it worked.
I build what I design. React and Astro front ends, Shopify and Webflow, and the automation that keeps it all running.
Not just prompts. I build automated workflows that run on their own across design, product and code, and stop where a decision needs me.

Human in the loop
I build systems, not just features. Products that look good, feel obvious and actually perform.
Behind every product that scales is a system: a design system the team can build on, data that shows what works, and automations that take the busywork off everyone's plate. That's what I set up, so teams ship faster with fewer handoffs and less manual work.
Design, product or code: I can step in wherever the system needs it. That range comes from an HCI master's at LMU, a paper at ACM CHI, and ten years at Agrando, VIU, AutoScout24 and koorvi, the company I co-founded.
