Helping customers to reach their goals by making the best use of technology is what motivates me. I am an IT infrastructure specialist and architect with over 15 years of experience in various roles within Professional Service and now Customer Success organizations, all customer-facing. As one of roughly 300 VMware Certified Design Experts worldwide, the certification was granted to me after defending a production-ready IT-architecture solution before a veteran VCDX accredited panel with the goal of validating technical, design and critical thinking skills.

Always willing to learn and help out, I evolved my knowledge to cover infrastructure technologies (compute, storage, network, bc/dr, …), automation (e.g. terraform, python) and container technologies (Kubernetes) in the public cloud and on-premises. Starting out with Linux early in my career has provided me with the fundamental knowledge (linux services, iptables, shell scripting, monitoring, …) that is now part of every SRE/DevOps toolset. I take pride in my ability to work self-motivated and on my own initiative. As part of a team, my aim is to lift everyone up rather to stand out.

My free time, when not devoted to my family, is spent with exercising and reading.
