Top SchoolYuhang Qyh is a 技术专家 with 10 years’ experience focused on database kernel development, currently working on PolarDB at Alibaba Cloud in Hangzhou. He brings deep expertise in database theory, PostgreSQL internals, OS kernel interactions, and performance tuning, having progressed from intern to senior engineer and now technical expert within the same team. His background in software engineering from Tongji University underpins a practical, systems-first approach to solving high-throughput, low-latency challenges. Colleagues rely on him for bridging theory and production—optimizing core storage and execution paths rather than just application-level improvements. Notably, his continuous in-team growth suggests strong ownership and the ability to deliver long-lived, scalable database features at cloud scale.
