PROFILE

Chris Barker

Worked on stabilizing Windows 64-bit builds in the conda-forge/admin-requests repository by introducing a YAML-based risk mitigation strategy. Addressed a recurring CI/CD issue by creating the pygnome-broken.yml configuration, which explicitly marks and excludes known failing versions of the pygnome package for Windows 64-bit environments. This approach prevented build failures and reduced CI noise by preemptively avoiding problematic package combinations. Leveraged skills in CI/CD configuration and YAML to implement a scalable solution that can be reused for future build breakage scenarios. The work focused on improving reliability and maintainability of the build process without introducing new features.
