Top SchoolZhibai Song is a software engineer with a decade of experience building and optimizing cloud-native databases and high-consistency systems. He has deep, hands‑on expertise in both MySQL and PostgreSQL engine development and has been a core contributor to cloud database projects including PolarDB and Amazon Aurora. At AWS he worked on Aurora MySQL serverless and Aurora PostgreSQL features such as serverless transactions and Babelfish execution support, while at Alibaba Cloud he helped design a fully MySQL‑compatible shared‑disk PolarDB with parallel query optimizations.
