During February 2026, Just Gook focused on backend development for the rclone/rclone repository, addressing a cross-origin resource sharing issue in the WebDAV middleware. By implementing a targeted patch in Go, Just added the necessary CORS headers to ensure proper interoperability for WebDAV clients, resolving a longstanding bug that hindered cross-origin access. The solution was carefully scoped to minimize changes while maintaining compatibility with existing tests and documentation. Drawing on skills in API development and CORS configuration, Just’s work improved the reliability of cross-origin requests in rclone, demonstrating a methodical approach to backend problem-solving within a mature codebase.
