Über Oliver

Seasoned IT leader with 15+ years building scalable systems and teams in regulated industries. As CTO, CPO, and CISO, I co-founded and led a health-tech startup from zero to market and served as CTO at a surgical-tech company. What sets me apart is a holistic approach — I'm equally at home in the boardroom shaping strategy and compliance frameworks as I am designing system and software architectures, writing Terraform modules, or debugging Kubernetes clusters. I implement ISO 27001 and ISO 13485 management systems, integrate machine learning into certified medical devices, and design the DevSecOps pipelines that keep everything running. Based between Berlin and Singapore, I consult on infrastructure, security, and compliance across DACH and APAC markets.
