Employee Management System

This is a full-stack web application for managing employees, built using Spring Boot and React Hooks. It covers basic CRUD operations (Create, Read, Update, Delete) and integrates MySQL as the database. The backend REST API is tested using Postman, and the frontend handles the API using Axios.
