Worked on enhancing the reliability of system log retrieval in the xerrors/Yuxi-Know repository by addressing encoding issues that previously caused failures during log analysis. Applied Python and asynchronous programming skills to enforce UTF-8 encoding when reading system log files, while also implementing logic to ignore encoding errors. This approach stabilized log ingestion and reduced operational incidents, improving the maintainability and reliability of the backend logging subsystem. Documented the encoding changes thoroughly to ensure backward compatibility and facilitate cross-team understanding. The work focused on backend development, resulting in safer log access workflows across diverse environments and contributing to overall technical robustness.
