About Andong Zhan

I’m a Staff Software Engineer at Snowflake working on large-scale data infrastructure and platform systems that support programmable and performance-critical workloads.Over the past several years, I’ve focused on building and evolving foundational components of the Snowflake platform, including execution models, security infrastructure for user-defined code, data semantics, and performance-sensitive paths that operate at cloud scale.My work spans system architecture, correctness, performance, and operability, with an emphasis on designing primitives that can support diverse workloads reliably in a multi-tenant environment.Earlier in my career, I completed a Ph.D. in Computer Science at Johns Hopkins University, where I worked on large-scale computing systems and applied machine learning, building end-to-end systems deployed in real-world healthcare settings.I enjoy working at the intersection of systems design, data platforms, and real-world impact, and collaborating across teams to turn complex requirements into robust, scalable infrastructure.
