Developed CRS Info, a bulletin board-styled progressive web application customized as an information broadcaster for PT Cipta Rasa Sempurna. The application was meticulously designed to selectively disseminate information based on user-specific characteristics: permissions and tags. Upon registration, users were assigned permissions and tags, enabling higher-tier users to manage permissions for new registrants.Permissions granted users authorization to access or modify specific modules (e.g., post, user), while tags served as keywords connecting posts and users. Users were prompted to tag their posts with specific keywords provided by the application (e.g., #management, #production, #public) during posting.Leveraging Firebase messaging and functions, CRS Info orchestrated a sophisticated notification system. When a user posted on a module, notifications were selectively dispatched only to users with matching permissions and tags, ensuring targeted dissemination of information.
