Worked on enhancing the Wallabag plugin within the koreader/koreader repository, focusing on improving reliability and lifecycle management. Addressed download error handling by implementing a centralized cleanup mechanism in Lua, ensuring that incomplete or empty files are removed when network or server errors occur. Developed a new remote option for deleting on-hold articles, allowing users to manage these separately from finished articles and improving overall configurability. Leveraged skills in configuration management, error handling, and plugin development to deliver these updates. The work resulted in higher data integrity, reduced invalid downloads, and more flexible user workflows for managing article states.
