Worked on the apache/incubator-devlake repository to enhance data quality and reliability within the CI/CD data pipeline. Addressed a specific issue in the cicd_job_convertor by implementing logic to skip GitHub CI/CD jobs that lack a started_at timestamp, thereby preventing errors and improving the accuracy of downstream analytics. Developed and integrated automated tests to ensure the skip behavior functions correctly and that jobs with valid timestamps are processed as expected. Utilized Go for backend development and applied CI/CD best practices throughout the process. The work resulted in cleaner CI/CD metrics and improved traceability for future data analysis and maintenance.
