Summary

Companies that work with their digital product every day develop a blind spot for UX and UI issues. I help e-commerce brands, B2B SaaS teams, and mid-sized companies make these issues visible—and fix them. My focus is on UI design, building design systems, and UX audits in Figma. I work with an experienced team of senior designers—projects are handled through my GmbH, legally secure and without any pseudo self-employment issues.

How I help: — Building and migrating design systems (components, tokens, documentation) — UI design for web, mobile, and complex B2B applications — UX audits: structured feedback on flows, conversion issues, and accessibility (WCAG) — Accessibility checks and WCAG-compliant implementation Clients: REWE, AXA, Douglas, Kaufland, Gothaer, Statista, Falke, Deutsche Telekom, and more. I don't just take tickets. I bring strategic judgment from 15+ years and 100+ projects—and deliver actionable results.
