Rockstar🎓
Top SchoolZhang Xitong is a software engineer with nine years of experience building high-performance data systems, currently at Microsoft in Beijing. He is the author of parquet-go, a Go library for reading and writing Parquet files, and Guery, a distributed SQL engine for big data, reflecting deep expertise in storage formats and distributed query execution. His parquet work has been integrated into notable projects like Gleam, where he implemented Parquet file reading support, demonstrating practical impact across the Go big-data ecosystem. Trained as a physicist with a PhD from Peking University, he brings a strong analytical background and attention to low-level data correctness and performance. Colleagues describe him as having “super coding power,” a fitting nod to his prolific open-source contributions and hands-on problem solving. He combines research-grade rigor with production engineering experience to deliver reliable, scalable data tooling.
