Rockstar🎓
Top SchoolFrédéric Simonis is a research associate and PhD candidate with 12 years of software engineering experience, specializing in high-performance scientific computing and open-source infrastructure. He is core developer and release manager of preCICE, a widely used coupling library for multi-physics simulations, and has driven core refactors, mesh and data-connection features, and robust test and build improvements. His background spans backend and full-stack work—from integrating gradient descent into an in-memory DB to improving cross-platform tooling in Sourcetrail and packaging in Spack—reflecting both deep systems knowledge and practical engineering. Based in Stuttgart and trained at TUM, he blends academic rigor with production-grade maintenance, often tackling build-system and dependency challenges that quietly keep projects shipshape. Colleagues rely on him for careful refactors and reproducible releases that enable complex fluid-structure and conjugate heat transfer simulations.

spack/spack
Apr 2019 - May 2022
A flexible package manager that supports multiple versions, configurations, platforms, and compilers.
Role in this project:Back-end Developer & Build Engineer
Back-end Developer & Build EngineerContributions:7 reviews, 21 commits, 33 PRs in 3 years 1 month
Contributions summary:Frédéric primarily focused on package management within the Spack ecosystem, specifically for the preCICE library. They added multiple versions of preCICE, updated dependencies, and resolved conflicts with various compiler versions. Additionally, the user contributed to build system improvements, including adding support for new CMake variables and incorporating the BUILD_TESTING flag. They also added a mirror environment documentation for improved accessibility.
