Developed a unified cluster validation and retrieval feature for the ydb-platform/ydb repository, focusing on backend development using C++. Implemented the GetValidClusters method to aggregate valid cluster configurations across multiple data source providers, enabling consistent cluster management and discovery throughout the system. This approach improved the reliability of cluster orchestration by reducing configuration drift and supporting scalable automation within deployment pipelines. The work emphasized cross-provider data access and API consistency, ensuring that cluster information could be retrieved efficiently and accurately. Leveraging expertise in C++ and backend systems, the solution contributed to more robust and maintainable cluster orchestration processes.
