Summary
🤩
Rockstar🎓
Top SchoolWu Yunlong is a Research and Development Engineer with eight years of hands-on experience building and hardening distributed key-value storage systems, specializing in Redis forks and cloud-native storage architectures. Based in Shanghai, he has driven performance optimizations, high-availability features, and memory-leak fixes for projects used at scale—contributing bug fixes and core changes to high-profile repos like redis/redis and KeyDB. At Meituan he helped evolve a Redis-based storage fork and later designed storage-compute separated systems, distributed blob stores, and automation tooling for cloud integration. His background in C++ and networked systems dates back to game and ad-retrieval engines, giving him a practical focus on low-latency, robust systems engineering. Notably, his open-source work includes fixes to RDB/AOF behaviors, replication and dict-resize policies that improve real-world stability under heavy load.
