About

Expertise

Brand-driven. System-built.

For over 15 years, I've worked both with digital agencies — including Jung von Matt, DDB, and Serviceplan — and directly with brands including Deutsche Telekom, BMW/MINI, Volkswagen, tesa, and Domino's.

Brand and product are usually handled by different people. I work where they meet: visual identity and interface logic as one system, from concept through to development handoff.

AI tools are part of how I work — across research, prototyping, and documentation. I use Claude Code, Figma AI, and CLI automation. I'm currently working on how design systems need to be structured so AI tools can work with them reliably.

Design Systems & Token Architecture

Token-based component systems built for real handoff — structured for cross-platform consistency and designed to be something development teams can actually work from.

Complexity → Clarity

Complex interfaces, information-heavy layouts, and ambiguous briefs — structured into clear, functional design solutions. The goal isn't simplification for its own sake, but finding the structure that makes the right things obvious.

Prototyping & AI-assisted Workflows

Research, concepting, component work, documentation — AI tools increasingly woven into each phase to run more parallel tracks and shorten feedback cycles without cutting corners.

UX/UI Design

Interaction design and iterative testing: functional, accessible interfaces grounded in user needs, with decisions made visible in prototypes before they become expensive in code.

Visual Design

Art direction, typography, motion — brand-specific visual language built to hold up across digital touchpoints, from style guide to production.
