Contributed to the DIYgod/RSSHub project by enhancing the 4chan route to deliver more relevant and user-focused content feeds. Developed catalog-level filtering features that exclude sticky threads and enforce minimum and maximum reply counts, effectively reducing noise and improving the quality of information presented to users. The implementation was carried out in TypeScript and Node.js, with careful attention to code maintainability and alignment with reviewer feedback. Throughout the process, maintained repository health by ensuring backward compatibility, clear documentation, and concise commit messages. No major bugs were addressed, but the work emphasized stability, code consistency, and improved user experience for RSSHub consumers.
