Developed and delivered an advanced article content filtering feature for the richard67/joomla-cms repository, enhancing the Joomla Admin interface to support retrieval and persistence of user-selected filters such as category, access level, author, tag, and language. This backend development work, implemented in PHP, focused on improving editorial workflows by enabling faster and more precise article management while maintaining filter state across sessions. The solution integrated backend filtering logic with UI state management and leveraged Joomla extension development practices. Version control was managed with Git, and the work involved effective cross-team collaboration to align with release milestones and project requirements.
