Worked on the Quantco/glum repository to migrate its packaging build system from conda-build to rattler-build, focusing on modernizing and streamlining the build and release process. Updated CI/CD configurations and packaging recipes using Python and YAML to ensure compatibility with the new tool, which centralizes and accelerates the packaging workflow. This migration improved build reproducibility and reduced ongoing maintenance by consolidating tooling, while also laying the foundation for future automation and faster release cycles. No major bugs were addressed during this period, with efforts concentrated on enhancing build systems and package management to support more efficient development practices.
