Worked on enhancing the redis/go-redis repository by delivering Universal Client support for failover clusters, focusing on improving reliability and availability in Redis deployments. Developed logic in Go to distinguish between FailoverClient and FailoverClusterClient within the Universal client, enabling routing strategies such as RouteByLatency and RouteRandomly when a MasterName is specified. Introduced automated tests to validate connectivity and routing behavior in failover scenarios, ensuring robust handling of cluster failover events. The work emphasized backend and full stack development skills, leveraging Go and Redis to provide configurable failover routing and comprehensive test coverage for high-availability Redis environments.
