Worked on the dockur/lemmy repository to enhance post content handling and improve backend data accuracy. Developed a feature in Rust and SQL that allows posts to support multiple attachments by appending link attachments after existing images, aligning with established attachment logic and adding comprehensive test coverage. Addressed analytics reliability by updating a scheduled database task to reset activity counts for inactive communities, preventing skewed metrics and ensuring accurate reporting. The work included code linting and maintainability improvements, resulting in more robust backend processes. These changes improved user content rendering, database management, and the overall trustworthiness of community activity analytics.
