# Marc Hinse

> Product Design Leader working at the intersection of product, design and technology. I make complex things make sense: for 20+ years turning tangled problems into systems people can understand, use and build on. Based in Karlsruhe, Germany, working globally.

This site is a portfolio, available in English and German. The projects are framed as arguments rather than conventional case studies.

## Pages

- [Portfolio (English)](/): positioning, selected work, beliefs, career
- [Portfolio (Deutsch)](/de/): the same site in German

## Selected work

- Product discovery as an AI-native process (Uptempo Discovery Agent): AI consolidates, clusters and drafts; people stay in the loop; a loop, not a line.
- A design system is not a library (UP UI / Frontend Foundation): rebuilt as an organizational and communication system, not a component shelf.
- Making two product worlds work as one (Platform integration): change management with a design surface, not a visual merge.
- The prototype as a thinking tool (Approval Workflows): modularize who, what and under which condition; validate the pieces, then reassemble.
