Rockstar🎓
Top SchoolZongzhi Chen is a Staff Engineer with 13+ years building high-performance distributed systems, storage engines, and network frameworks, currently leading Alibaba Cloud RDS initiatives. He previously led Qihoo 360’s infrastructure storage team where he drove development of Bada (a Dynamo-inspired NoSQL) and Pika, a Redis-compatible, large-capacity key-value store, and contributed core networking and protocol work in open-source projects like pink and pikiwidb. Proficient in C/C++, Erlang, and Linux toolchains, he combines deep systems-level optimization skills with practical algorithmic rigor. Notably, his hands-on contributions include TCP connection handling, core set/get operations, heartbeat/health features, and a custom epoll-based thread model—signals of a pragmatist who bridges theory and production reliability. Based in Chaoyang District, Beijing, he reads and learns from many open-source systems (LevelDB, Ceph, Redis, Aerospike) to continuously refine large-scale storage designs.
