Worked on modernizing the CI/CD workflows for the IAS-Astrophysics/athenak repository, focusing on delivering faster and more reliable builds through environment standardization and consolidated test execution. Addressed issues with GCC toolchain loading, lint test path alignment, and log file management to ensure consistent and predictable CI runs. Improved Anaconda module handling and maintained comprehensive documentation of all CI enhancements, supporting rapid feature delivery and reducing maintenance overhead. Utilized Python, Bash, and YAML to implement these changes, emphasizing automation and reproducibility. The work resulted in streamlined feedback cycles and a more maintainable CI/CD pipeline, directly benefiting ongoing development efficiency.
