Lichuang is a software engineer with extensive experience building distributed systems, databases, and storage engines. His work spans consensus protocols, replication, and cloud-native infrastructure. He is an active open-source contributor — most notably a committer on openraft, the leading Raft consensus library in the Rust ecosystem.

He is the author of Lua-Source-Internal, a widely-read deep dive into the Lua VM, compiler, and runtime — later published as the book Lua: Design and Implementation in both Simplified and Traditional Chinese. He shares more of his technical writing at codedump.info. His approach: cut through academic jargon, lean on diagrams, and help engineers grasp why systems behave the way they do — not just memorize how.
