Worked on the linkedin/rest.li repository to address a reliability issue in backend Java code, focusing on the FileStore.get() method. Identified and resolved a race condition that could cause IndexOutOfBoundsException during concurrent file access, which previously risked application crashes and unreliable data retrieval. The solution involved replacing the existing file-reading logic with a safer, more robust approach, enhancing the stability of file operations for consumers. Demonstrated skills in Java, backend development, and concurrency debugging while collaborating through code review and pull requests. The work emphasized robust I/O handling and contributed to improved reliability in a production backend environment.
