About
Clear leadership, products people love, and AI for the boring parts.
Give me the tangled stuff: unclear goals, too many stakeholders, a deadline that was yesterday. I bring people together, make the hard calls clear, and build teams that ship. Fewer slides, more working software. And people tend to enjoy the ride.
- 25+people led across design, product and engineering
- 40+products and features shipped
- Now elyvatelive An AI-powered product execution platform
-
01
Inspire
Vision, clear direction and a team that wants to get there. Understanding the needs of users and teams before making the product.
-
02
Build
From prototype to production with engineers and AI. Hands-on when it counts.
-
03
Repeat
Ship, listen, learn, improve. Good products are never done, and neither are good teams.

Since July 2026, I lead elyvate at AlixPartners as Platform Director. With the foundations in place, we now scale it as an AI-powered product execution platform across industries. Together with a team of designers, product managers and engineers, we bring AI into how complex programs are planned, tracked and delivered, for AlixPartners and its clients.

Then AlixPartners acquired Berylls, and our mission changed. We hardened elyvate for a global firm, prepared it for AlixPartners’ infrastructure and opened it up beyond automotive. elyvate grew from an automotive PMO tool into an industry-agnostic product execution platform.

When Berylls brought its digital unit under one brand, elyvate moved with it. Leading the product, I helped shift our focus from a working MVP to an enterprise-ready SaaS solution, built to scale and to sell.

As Lead Designer of willhaben’s mortgage vertical, I helped take the product from zero to one. We challenged how things were done, built our own design library and enabled product managers and developers to work with design every day. The vertical closed in early 2026, but it showed what a small, cross-functional team can build from scratch.

As a design consultant, I helped the team behind Signal Iduna Gesundheitswelt work in a truly user-centred way. We brought user research into the process, ran large surveys, launched internal and external tools and redesigned the website.

As a freelance designer in the Shui design system team, I pushed for change. We modernised how Healthineers designs its digital products and prepared the move to Figma, including interfaces embedded in medical hardware.
