Complaint Management System using Spring Boot, React

Description

The Complaint Management System is a complete full-stack web application designed to manage and track complaints within an organization in a structured and efficient way. This project is built using Spring Boot (backend), React (frontend), and MySQL (database), making it a modern industry-level solution suitable for final year submission and real-world understanding.

This system includes three main modules: Head of Department (HOD), Employee, and Engineer. Each user role has its own dashboard, login system, and permissions. Employees can raise complaints and track status. Engineers can view assigned tasks and update resolution status. The HOD can monitor all complaints, assign tasks to engineers, and manage the engineering team.

The backend is developed using Spring Boot REST APIs with proper layered architecture (Controller, Service, Repository). The frontend is developed as a React Single Page Application using Axios for API communication and Bootstrap for styling. The database is managed using MySQL with proper relational schema and sample data.

This project is ideal for BCA, B.Tech, MCA, and MSc IT students who want a professional-level project that demonstrates full-stack development skills, REST API integration, and role-based access management.
