I help product teams get unstuck.
After 25 years leading design at companies like Amazon, 1&1, and various B2B startups, I've seen the same patterns repeat: teams with talented people who can't ship, products with potential that somehow never reach it, organizations where design is present but not effective.

The problems are rarely about pixels. They're about clarity, alignment, and the invisible work that happens before anyone opens Figma.
Who are we building for? What does success look like? Why does every decision feel like a battle?

I work at three altitudes:

Strategy
Aligning design work with business goals, defining what "good" looks like, building the case for user-centered thinking at the leadership level.
Process
Introducing structure without bureaucracy. Research that informs decisions. Reviews that improve work. Handoffs that don't require telepathy.
Craft
When needed, I still design. Complex workflows, design systems, the kind of enterprise interfaces where details compound into experience.

I also practice what I recommend. This website and the CV tool I use were built with Claude Code as a development partner. The only way to understand where AI actually helps (and where it generates confident nonsense) is to use it on real work. That experience informs how I advise teams exploring AI-augmented workflows.

My best work has been in B2B and enterprise environments: digital asset management platforms, industrial robot configurators, property management systems, global service networks. These are domains where users are experts, workflows are complex, and "intuitive" means something different than consumer apps.

I'm based in Munich and work with teams across Europe. Whether it's a 6-month sprint or an 18-month transformation, the goal is the same: fix the broken system, build the capability, hand off something sustainable.

I take on transformation initiatives where the goal is clear: fix the broken system, build the capability, hand off to your team. Whether that's a focused 3-month sprint or a comprehensive 18-month rebuild depends on what you're trying to solve. If your team is stuck and you need someone who's solved this before, let's talk.
