Contributed to percona/percona-server-mongodb by developing features and reliability improvements focused on sharding, resharding, and migration workflows. Enhanced observability and error handling for data migration, enabling faster diagnostics and clearer post-mortems. Improved sharding robustness by refining error semantics and expanding integration tests for concurrent operations. Delivered cross-platform stability through macOS build fixes and hardened test suites for transaction and resharding scenarios, reducing CI flakiness. Advanced resharding reliability by standardizing concurrency primitives and increasing oplog capacity. Expanded JavaScript-based integration tests for mongos retry logic, strengthening backend resilience. Work leveraged C++, JavaScript, and MongoDB, emphasizing backend development, testing, and database management.
