Top SchoolHans-nikolai Viessmann is a systems engineer and scientific computing specialist with 12 years of experience building and operating HPC platforms for research, currently helping deploy next-generation HPE Cray Shasta systems at the Paul Scherrer Institut. He pairs deep compiler and many-core/GPU expertise from his PhD work—where he produced compiler-driven CUDA code generation and memory orchestration—with hands-on cluster administration and Kubernetes-driven, stateless research application modernization. Fluent in English and German and having worked across four countries, he excels at bridging academic research and production infrastructure to deliver measurable performance gains. An electronics hobbyist and avid cyclist who is finishing his PhD thesis, he brings both practical operational rigor and a researcher's knack for low-level optimization and system design.
