Khi worked on the farm-fe/farm repository, focusing on improving the reliability of external module import resolution. During this period, he addressed a high-priority bug that caused duplication of query strings when resolving external dependencies. By refining the plugin resolve hook to use the original source string, he eliminated redundant query parameters and ensured accurate referencing of external modules. This change enhanced the determinism and correctness of the module resolution pipeline, directly impacting build stability. Khi applied his expertise in Rust, build tools, and module resolution, delivering a targeted fix that improved the overall reliability of dependency management within the project.
