Overview

Mediahub is a full-featured microservices messaging platform built with Spring Boot. It supports real-time communication through WebSocket STOMP, AI-powered chatbot interactions using Retrieval-Augmented Generation (RAG), and robust security features like JWT authentication and rate limiting. The services are containerized using Docker, managed automatically with Jenkins CI/CD pipelines, and deployed onto a Kubernetes cluster. The distributed data layer integrates MongoDB for message storage, PostgreSQL for user directories, and Redis for caching and session state.
