What I'm looking for

I'm looking to lead complex infrastructure, cloud, data centre, or enterprise technology programmes where I can apply structured governance, cross-functional leadership, and zero-downtime delivery in an international environment.

I've delivered data centre, cloud, and enterprise technology programmes for global organisations, principally SAP SE. My work combines structured project governance with hands-on understanding of infrastructure operations and service delivery.

At SAP, I led the merger of acquired customer landscapes and relocated a data centre from Germany to the Netherlands with zero operational downtime and full regulatory compliance. I also managed cloud infrastructure operations, executive customer escalations, and tenant-cleanup initiatives that consolidated redundant environments.

I led multi-million-euro data centre infrastructure builds for blue-chip customers, coordinating up to 30 IT professionals, architects, and vendors across international locations. I was recognised with a Spot Award for rescuing and delivering critical client projects.

My experience also includes infrastructure, security, compliance, and critical-operations projects with Loomans & Matz, PwC, and Deutsche Bahn. I'm PRINCE2, SAFe Scrum Master, and ITIL certified, with an MBA and experience leading delivery in highly regulated environments.
