Worked on the apache/celeborn repository, delivering features and fixes that enhanced backend reliability and maintainability. Implemented advanced data splitting with HARD_SPLIT support in PushMergedData, improving shuffle robustness under disk-full and partition-split scenarios. Refactored status code handling by replacing legacy conversion logic with a more maintainable approach, simplifying future updates. Addressed concurrency and error handling by ensuring proper propagation of InterruptedException and improving error message clarity, reducing troubleshooting time for users and engineers. Utilized Java, Protocol Buffers, and Scala, applying skills in distributed systems, API refactoring, and unit testing to strengthen code quality and operational stability throughout the project.
