- I solve whatever is stuck in procurement, logistics, and operations.
- I help mid-sized and growing companies identify and eliminate bottlenecks along their value chain, such as chaotic procurement processes, stalled logistics, or overloaded day-to-day operations.
- My work is based on 15+ years of leadership experience in international supply chains, medical technology, and the event business.
- In 2025, I launched Ultreia: a workshop format that helps companies turn vague project ideas into concrete, actionable roadmaps.
- I don't sell effort, I sell results, and I build my consulting model around that.

Summary
If your supply chain is stuck, I can help.
Whether it's chaotic procurement processes, exploding logistics costs, or stalled production workflows - I help mid-sized companies regain structure, efficiency, and momentum.
What I bring 15+ years of leadership experience in procurement, logistics, operations, and supply chain management - in international mid-sized companies, in medical technology, and in the event business. I have built, realigned, and fixed supply chains. In Germany, Europe, Asia, and the USA.
How I work Pragmatic. Hands-on. Result-oriented. I don't deliver slides, but solutions. Whether in the form of a compact diagnostic workshop, a clearly defined project, or temporarily in a leadership role (some call it interim management, I call it taking responsibility).
Let's talk if … ...you need clarity and structure in your processes ...you're growing but your processes can't keep up ...you're tired of consulting without results
