Worked on the oracle/coherence repository to address a critical issue in the Datagram-test Tool, focusing on improving test reliability and metrics accuracy. The solution involved encoding the packet sequence number directly into the payload, enabling the listener to accurately track sent packets and resolve incorrect success rate reporting. Developed and integrated a new unit test to verify the correct formatting of packet counts, including scenarios with large values, thereby expanding coverage for edge cases. Demonstrated strong skills in Java development, debugging, and test-driven development, with an emphasis on robust testing and code review practices to strengthen release validation processes.
