As a cornerstone project in my portfolio, it showcases advanced backend development techniques and a deep understanding of modern cloud-native patterns.</p> <p>This project serves as a practical guide to service decomposition, inter-service communication, centralized configuration, and robust security in a distributed environment.</p> <h3 id="key-architectural-features">Key Architectural Features</h3> <ul> <li><strong>Service Decomposition</strong>: The system is broken down into independent, domain-driven microservices, each with its own database and logic. <ul> <li><strong>Employee Service</strong>: Manages core employee data and handles user authentication.</li> <li><strong>Payroll Service</strong>: Processes detailed salary and payroll information.</li> <li><strong>Leave Service</strong>: Manages employee leave requests and approvals.</li> </ul> </li> <li><strong>Service Discovery</strong>: Utilizes <strong>Netflix Eureka</strong> as a service registry, allowing services to dynamically find and communicate with each other without hardcoded endpoints.</li> <li><strong>Centralized Entry Point</strong>: A <strong>Spring Cloud Gateway</strong> acts as the single entry point for all client requests. It is responsible for routing, load balancing, and cross-cutting concerns like security.</li> <li><strong>Decentralized Security</strong>: Security is enforced at the gateway level using <strong>Spring Security</strong> and <strong>JSON Web Tokens (JWT)</strong>. The gateway validates tokens before forwarding requests to downstream services, ensuring the entire system is secure.</li> </ul> <h3 id="core-technologies">Core Technologies</h3> <ul> <li><strong>Backend</strong>: Java 21, Spring Boot 3</li> <li><strong>Microservices</strong>: Spring Cloud Gateway, Netflix Eureka</li> <li><strong>Security</strong>: Spring Security 6, JWT (JSON Web Tokens)</li> <li><strong>Database</strong>: Spring Data MongoDB (for data persistence)</li> <li><strong>Build</strong>: Apache Maven</li> </ul> <p>For a detailed explanation of the architecture, API endpoints, and setup instructions, please visit the <a href="https://github.com/Prajwal-banakar/Employee-System">Employee-System GitHub Repository</a>.</p>
