Worked on the Netcracker/qubership-apihub-backend repository to deliver a targeted robustness enhancement for package move operations. Focused on backend development using Go, the work introduced enhanced validation logic and error handling for destination packages during move actions. This included addressing edge cases such as when a destination exists but is deleted, and preventing moves to already present destinations. By strengthening data integrity and reliability, the update reduced invalid transitions and improved overall system robustness. The implementation emphasized clear error messaging and maintainable code, leveraging skills in API development and database interaction to ensure traceability and long-term maintainability of the backend.
