Developed a real-time messaging system for a Node.js application, supporting multi-channel communication including public, private, and direct messages. Enhanced scalability and distribution by designing message routing across sub-servers. Implemented multi-threading and load balancing using Redis and RabbitMQ to manage high traffic efficiently. Established a dynamic, role-based access system for channel membership based on assigned permissions. Automated membership management and real-time permission control through server-side role mapping. Boosted system performance and reliability in a distributed setting via caching strategies and message queueing.
