PROFILE

Worked on the trinodb/trino repository to enhance directory listings cache invalidation by incorporating schema and table names into the cache key, ensuring that invalidations targeted only relevant data and prevented cross-table purges in shared path scenarios. Applied expertise in Java, caching, and concurrency to strengthen the cache invalidation workflow under concurrent access, making directory listing tests thread-safe through the use of AtomicInteger and volatile flags. This approach reduced the risk of stale data and improved cache hit rates, while also increasing test reliability. The work demonstrated a strong focus on distributed systems, file system management, and robust testing practices.
