Zhuo Zhi is a back-end software engineer and database specialist with 8 years of experience, based in Sunnyvale, California. He contributes to the high-profile open-source TiDB project, focusing on partition pruning, query optimization, and robustness improvements like point get and batch get correctness tests. With an MS in Computer Science from UC San Diego and a BE in Electrical Engineering from Xi'an Jiaotong University, he blends rigorous academic training with practical systems engineering. His work improves performance and correctness in cloud-native distributed SQL databases, a niche that requires deep understanding of query planners and storage semantics. Notably, he has implemented targeted optimizations for hash, range, and list partitions that reduce unnecessary predicates and streamline query paths. He pairs research-driven problem solving with production-focused implementation to make large-scale databases more reliable and efficient.
