PROFILE

Marcel Schilling

During a two-month period, Michael Schilling focused on stabilizing the conda-forge/conda-forge-repodata-patches-feedstock repository by addressing compatibility and reproducibility issues in the Statsmodels package. He implemented targeted dependency management strategies, including precise SciPy version pinning in YAML configuration files, to prevent downstream build failures and maintain cross-version compatibility. His work involved correcting metadata, adding missing hashes for integrity checks, and broadening accepted build numbers to reduce unnecessary build errors. Leveraging skills in build systems and package management, Michael delivered maintenance patches that improved the reliability of the feedstock, demonstrating a methodical approach to configuration management and ecosystem stability.

In July 2025, delivered a stability-focused patch to conda-forge/conda-forge-repodata-patches-feedstock by implementing a SciPy compatibility pin for statsmodels. The change pins SciPy to <1.16.0 while supporting >=1.4 and explicitly excluding problematic 1.9.2, resolving reported compatibility issues and preventing breakages across downstream environments. This aligns with our goal of maintaining cross-version compatibility and reproducible builds in the conda ecosystem.
