During November 2024, Jibing Li enhanced the apache/doris-website repository by refining Chinese documentation for Join Hints, clarifying the use of Leading and Distribute Hints to support developer onboarding and query optimization. In the Jibing-Li/incubator-doris repository, Jibing Li implemented new backend features enabling cancellation of long-running load, export, and warm-up jobs within the Nereids framework.

The contributions focused on backend development, SQL parsing, and technical writing, demonstrating depth in both documentation and runtime management improvements.
