Worked on stabilizing MIME parsing in the linkedin/rest.li repository, focusing on improving reliability and performance under production load. Addressed a recurring issue by implementing null checks in the MIME parsing logic, which prevented NullPointerExceptions and reduced exception overhead by approximately 1,700 traps per second for common requests lacking a q parameter. This change preserved existing business logic while enhancing throughput and lowering latency. Collaborated with cross-team reviewers to ensure maintainability and code health. Utilized Java for backend improvements and applied skills in error handling, Bash scripting, and performance optimization to deliver a targeted bug fix that improved system stability.
