Summary
🤩
Rockstar🎓
Top SchoolSergey Kosukhin is a Scientific Programmer based in Hamburg with 10 years of experience building high-performance scientific software and HPC deployment workflows. At the Max Planck Institute for Meteorology he led modernization of weather and climate modelling infrastructure, contributed significant Spack package-manager improvements, and helped standardize builds for the ICON model used by national forecasting services. His background combines a PhD in Computational Science with hands-on research software engineering from academic and industry projects, including numerical simulation systems for flood prevention and marine navigation. Sergey blends low-level build-system and dependency-management expertise with domain-level work on a DSL for weather and climate models, making complex codes more portable and user-friendly. He has a track record of automating reproducible HPC experiments and collaborating closely with domain scientists and industrial partners. Notably, his open-source contributions to spack/spack include adding and maintaining core scientific packages and fixing compiler-wrapper and environment issues that improve reproducibility across HPC platforms.
