With over 25 years experience In the full breadth of ICT infrastructure — from networks, storage and virtualization to cloud, data center architecture and security — I bring in-depth technical expertise that is rare in its completeness and applicability.
Where many specialists focus on one domain, I oversee the whole. Especially in complex environments, where systems, suppliers and interests intersect, I bring calm, structure and realistic solutions. My strength lies in understanding the technical details without losing sight of the bigger picture.
Whether it's migrating to a hybrid cloud environment, reviewing an RFP, or designing a twin-core data center — I deliver clear analyses, strategically substantiated choices, and designs that not only work on paper, but also in practice.
