Worked on FreshRSS/FreshRSS and php/doc-en repositories, focusing on backend stability and documentation clarity. Enhanced the FreshRSS installation process by re-enabling and stabilizing database status checks, ensuring required tables and columns exist while allowing for extension-added columns. Improved internationalization and addressed PostgreSQL compatibility, expanding multi-database support and reducing deployment risks. In php/doc-en, clarified XML documentation by specifying the need to manually escape the '&' character in SimpleXml::addChild(), reducing confusion and runtime errors. Utilized PHP and XML handling skills, with attention to database management and clear documentation. Delivered two features in one month, emphasizing robust workflows and maintainability.
