PROFILE
Changlei Li
Over a three-month period, contributed to the xapi-project/xen-api repository by delivering features and fixes focused on backend reliability, high availability, and API consistency. Worked extensively with OCaml to enhance VM lifecycle management, improve task scheduling, and align API versioning across host and pool interfaces. Addressed issues such as VBD leaks and data loss by implementing robust resource cleanup and resilient shutdown procedures. Improved observability and error handling through targeted logging and timeout mechanisms, while ensuring data model and schema alignment for smoother upgrades. The work demonstrated depth in backend development, database management, and virtualization, supporting safer and more reliable operations.
