Worked on the libnyanpasu/clash-nyanpasu repository to enhance configuration persistence and runtime reliability. Addressed a bug where the 'allow-lan' and 'log-level' settings were not correctly saved by aligning Rust backend data structures with TypeScript IPC bindings, ensuring kebab-case naming consistency throughout the serialization process. This approach improved cross-language data modeling and reduced configuration drift, resulting in more predictable application behavior across restarts. Demonstrated fullstack development skills by integrating Rust and TypeScript, focusing on IPC and schema-driven configuration. The work prioritized stability and correctness, contributing to a more robust system with fewer post-release defects and improved maintainability.
