Top SchoolSebastian Plattner is a System Architect based in Münsingen, Switzerland with 12 years of experience designing and operating Linux- and cloud-native platforms, with a strong focus on Kubernetes, security, networking and monitoring. He currently leads cloud-native and Kubernetes architecture at Puzzle ITC and co-founded acend gmbh to deliver training and hands-on expertise in DevOps and system engineering. Earlier roles include leading a cyber security products team at RUAG where he built network traffic analysis products, managed lab and production networks, and mentored apprentices—demonstrating both product delivery and people leadership.

His background in applied mathematics and long-standing work on network-focused tooling give him a detail-oriented, measurement-driven approach to system design.
