Learning Spring and Spring Security Through an EMS System

I wanted hands-on experience with Spring Security, so I built an Employee Management System with secure API layers.

Features I Implemented

• JWT-based login
• Role-based authorization
• CRUD operations for employees
• Repository and service layers following best practices

What I Learned

• Spring MVC routing
• Security filter chain
• How authentication differs from authorization

This project strengthened my understanding of Spring as a backend framework.
