Worked on enhancing the reliability of the Git data extraction pipeline in the apache/incubator-devlake repository by addressing error handling within backend components. Focused on replacing panic calls with structured error propagation in Go, the changes targeted repo_cloner.go and repo_collector.go to ensure that critical failures during repository cloning and data collection were logged and surfaced as errors rather than causing abrupt process termination. This approach improved the observability and maintainability of the ETL workflow, enabling faster diagnosis of missing data issues. The work demonstrated a strong emphasis on backend development, robust error handling, and effective use of Go for system stability.
