Worked on the slac-lcls/lcls2 repository to enhance the CI/CD workflow for the psana module, focusing on improving reliability and developer feedback in continuous integration. Introduced an environment variable for LCLS calibration within the conda workflow and updated GitHub Actions to streamline test execution, environment variable management, and build steps. Leveraged Python and YAML to implement a dedicated build step with comprehensive test coverage, which helped reduce flaky test cycles and accelerate issue detection. The work emphasized stabilizing the CI pipeline, improving reproducibility, and delivering faster feedback, with all efforts directed toward backend infrastructure rather than user-facing bug fixes.
