Summary
I'm not the consultant who sticks to PowerPoint slides. I'm the one who goes down into 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 corporate groups in security-critical IT projects – where responsibility, structure and decisive action are needed. As an experienced IT project manager, program lead and interim manager, I take charge exactly in the situations where others hesitate: migrations, crises, compliance audits, complex transformations, or building robust IT infrastructures.
I blend strategic thinking with hands-on depth – paired with a strong understanding of people, organizations and dynamics. My clients appreciate my calm, goal-focused approach, my analytical mindset and my ability to keep a clear head even under pressure.
My view of leadership is clear: leadership is about providing direction, making decisions and empowering others to take ownership. It means understanding systems – both technical and organizational – and shaping them for lasting impact. I never go for quick fixes, but focus on long-term stability, security and effectiveness.
My role? I'm a bridge builder between management and IT, a translator between tech and the executive level, a steady anchor in tense times and the engine for clear execution. I set things in motion – and bring them to completion. With intelligence, integrity and reliability.
