Worked on the clash-verge-rev/clash-verge-rev repository to enhance the reliability and observability of the proxy subsystem using Rust and backend development skills. Focused on addressing a critical issue where the system proxy state could be misreported if the toggle operation failed, implementing a targeted bug fix to ensure accurate state reflection. Added error logging for proxy connection closures, improving the system’s diagnosability and supporting faster root-cause analysis. These changes reduced the risk of incidents related to proxy misreporting without altering user-facing features, demonstrating a methodical approach to backend stability and operational transparency within a complex Rust-based codebase.
