Worked on the LMCache/LMCache repository to enhance system stability and reliability by addressing critical backend issues over a two-month period. Focused on Python-based backend development, the work included fixing a crash in the wait_for_save function when retrieval from the lmcache_engine failed, improving error handling and logging to reduce downtime for LMCache-dependent workloads. Additionally, resolved memory leaks in both the cache_engine and EIC connector, optimizing code and expanding unit test coverage to prevent regressions. These efforts improved memory stability and performance under load, ensuring more resilient production workloads and maintaining high code quality through careful review and code hygiene.
