PROFILE

Chris Barker

Worked across conda-forge and pydata/xarray repositories to deliver packaging improvements, CI stability, and cross-platform support. Developed and maintained conda recipes for packages like PyOpenGL-accelerate, xarray-subset-grid, and geometry_utils, using Python, YAML, and TOML to modernize build systems and metadata. Addressed CI failures by introducing risk mitigation patterns, such as YAML-based exclusion of problematic Windows builds, and restored macOS CI reliability through configuration management. Enhanced cross-platform compatibility by updating Pixi configurations for macOS in xarray. Emphasized reproducible builds, maintainable workflows, and clear documentation, reducing downstream build failures and supporting maintainers with traceable, version-controlled changes.

In October 2025, focused on packaging reliability for the conda-forge/staged-recipes repository by updating the Geometry Utils packaging to version 0.1.0. This work ensured reproducible builds and smoother downstream distribution by aligning the recipe metadata with the upstream release. The change was implemented in a single commit that bumped geometry_utils to 0.1.0 and updated the SHA256 checksum to match the new tarball, guaranteeing integrity of the built package.

December 2024 monthly summary for conda-forge/admin-requests: Implemented Windows 64-bit Build Breakage Risk Mitigation by introducing pygnome-broken.yml to explicitly mark and avoid known failing Windows 64-bit pygnome package versions, thereby preventing CI/build failures. This work stabilizes Windows builds, reduces CI noise, and establishes a scalable pattern for future risk mitigation.
