Summary
I'm not the consultant who sticks to PowerPoint presentations. I'm the one who goes down to the engine room with you – and makes sure your ship stays on course in any weather.
For over 25 years I've supported companies, authorities, and corporations in security-critical IT projects – where responsibility, structure, and decisiveness are needed. As an experienced IT project manager, program lead, and interim manager, I take charge in the situations where others hesitate: migrations, crises, compliance audits, complex transformations, or building robust IT infrastructures.
I combine strategic thinking with operational depth – paired with a deep understanding of people, organizations, and dynamics. My clients appreciate my calm, goal-oriented approach, my analytical thinking, and my ability to keep a clear head even under pressure.
My leadership philosophy is clear: leading means providing direction, making decisions, and empowering others in their responsibilities. It means understanding systems – technically and organizationally – and shaping them sustainably. I'm not interested in short-term activism, but in long-term stability, security, and effectiveness.
My role? I'm a bridge-builder between management and IT, an interpreter between tech and the board level, a calm anchor in tense situations and a driving force for clear execution. I get things moving – and finish them. With insight, integrity, and reliability.
