Worked on the devguard repository to enhance the reliability of SBOM ingestion by improving error handling in backend API endpoints. Focused on the SBOM scanning workflow, the developer modified the ScanDependencyVulnFromProject and ScanSbomFile endpoints to return a 400 Bad Request when clients upload SBOM files in an invalid format, replacing the previous 500 Internal Server Error response. This change, implemented in Go, strengthened input validation and clarified error feedback for clients, reducing confusion and improving the overall robustness of dependency vulnerability reporting. The work demonstrated attention to backend development, API design, and precise error handling within a production environment.
