Worked on the percona/percona-server-mongodb repository to deliver new QueryStats features focused on insert and change stream statistics, enhancing observability and reliability across sharded environments. Leveraged C++ and JavaScript to implement stable hashing for insert command shapes and aggregate insert statistics, while expanding test coverage to include writeConcern in QueryStats keys and simulate partial write failures. Refactored internal code paths and streamlined test infrastructure, improving maintainability and reducing production risk during upgrades and downgrades. Emphasized backend development, database management, and performance optimization, ensuring robust test automation and future scalability through thoughtful software architecture and targeted code improvements.
