About us

Two perspectives, one stance.

Clarity in thinking. Consistency in action. Two independent careers that meet in a shared way of working.

Solution Architect & Founder View LinkedIn profile ↗

Since 1999 I have moved through SAP landscapes — from introducing new CRM systems to international rollouts and major M&A integrations at SAP SE itself. More than 25 years in IT, over two decades of it in the SAP ecosystem, have taught me one thing: transformations succeed where process understanding, technical precision and the will to implement come together.

As Chief Product Owner and Solution Architect at SAP SE, I was responsible for private and public cloud solutions covering fulfillment, billing and subscription management. In M&A projects — including the integration of Qualtrics, Callidus, Fieldglass, Concur and Ariba — I learned how to bring systems together under time pressure and regulatory constraints without operations grinding to a halt.

Today I bring that experience into your S/4HANA transformation, your integration project or your process programme — pragmatic, direct, and focused on what ultimately has to work in practice.

For more than 25 years I have supported companies and institutions through complex business change — with strategic clarity, operational structure and a consistent focus on tangible business impact.

Whether repositioning, turnaround or digital realignment: what matters is that change works — efficiently, at the required scale, and with lasting results. Drawing on experience across more than a dozen industries and every level of leadership up to the C-suite, I help shape business and IT structures with a long-term perspective.

I bring complex situations to the point quickly, set clear priorities, and develop implementation strategies that hold up in practice. That is where my greatest impact lies: keeping the overview while moving exactly the levers that enable real change.

What sets me apart? Clarity in thinking. Consistency in action. Analytical depth, practice-oriented implementation and open, purposeful collaboration.
