PROFILE
Bo Lee
Over a two-month period, contributed to the kvcache-ai/Mooncake repository by developing high availability features for the master service. Built an etcd high availability interface wrapper in Go, introducing new methods for key-value management, prefix-based key watching, and snapshot handling to improve system resilience and scalability. Subsequently, implemented a hot standby mode with an OpLog interface, enabling faster failover and safer data replication. Enhanced the backend with batch key-value creation, OpLog management, and replication metrics monitoring, supporting robust observability and performance. Focused on backend development, distributed systems design, and database management, delivering foundational improvements for production-scale reliability.
