Worked on the RSSHub repository to enhance the reliability of weekly recommendations caching by addressing a race condition in the cache write process. The solution involved ensuring all asynchronous operations were properly awaited before data was stored, which reduced the occurrence of stale or inconsistent cache entries and improved the freshness of recommendation data. This work required careful debugging of the cache layer and demonstrated strong proficiency in asynchronous programming and backend development using TypeScript. The focus on API integration and robust async/await handling contributed to a more stable caching mechanism, directly benefiting the consistency and reliability of the RSSHub service.
