CRO and A/B testing as craft. Experimentation programs with Adobe Target and GA analytics for Lindt, Samsung and global brands. I defend a layout in a number, not a vibe.

What I do
CRO and A/B testing as craft. Experimentation programs with Adobe Target and GA analytics for Lindt, Samsung and global brands. I defend a layout in a number, not a vibe.
Design to code to PR to live. Next.js, React and Tailwind via Claude Code. I've built e-commerce products end-to-end, solo — no handoff over the wall.

About
I've spent 20+ years building, leading and growing interdisciplinary teams across UX/UI, e-commerce, analytics, SEO and tech — for Mastercard, Samsung, Bayer, Lindt and more. I coach juniors, challenge seniors, and build trust with dev teams in almost any stack.
Lately I build commercial products end-to-end with AI-assisted design and development — closing the gap between idea and production while keeping quality high.
