ProjectHub

ProjectHub is a high-performance, full-stack project management platform designed to streamline team collaboration. It provides a centralized dashboard for planning, tracking, and managing projects with real-time updates and a highly responsive user experience.

🏗️ System Architecture

The platform was engineered with a focus on security, scalability, and clean separation of concerns:

• Frontend (React.js): Built with React and styled using Tailwind CSS and Shadcn UI to deliver a professional, intuitive, and highly responsive user experience.
• Backend (Spring Boot 3.x): A high-performance REST API built in Java 17+ that manages core business logic, task assignments, deadline calculations, and real-time data persistence.
• Authentication Layer (Spring Security & JWT): Secures the application using stateless JSON Web Tokens. It utilizes a custom Spring Security Filter Chain (intercepting the Authorization header) and granular Role-Based Access Control (RBAC) to enforce ROLE_USER and ROLE_ADMIN permissions.

✨ Key Features

• Centralized Dashboard: A comprehensive, visual overview of project statistics, recent activities, and progress tracking at a glance.
• Advanced Task Lifecycle: Full CRUD capabilities for creating comprehensive projects, assigning individual tasks to team members, designating team leads, and setting strict deadlines.
• Collaborative Workflows: Keep teams aligned with real-time project tracking through dynamic status updates, task comments, and detailed activity logs.
• Robust Exception Handling: Implements global exception handling across the Spring API to ensure consistent and reliable error responses for the frontend.

🗄️ Database & Infrastructure

Data persistence is handled by MongoDB, a highly flexible NoSQL database. The application leverages Spring Data MongoDB with heavily optimized aggregations and indexing to ensure lightning-fast retrieval of complex project statistics and user activity logs, while maintaining strict data integrity across document collections.
