ROLE-BASED ACCESS CONTROL

Company HR Management System with Role-Based Security

I built a comprehensive HR Management System using Java and Spring Boot to streamline employee management, payroll processing, and leave request workflows. It features strict role-based access control with Admin having full system access, HR managing employee records and benefits, Managers approving leave requests and viewing team data, and Employees accessing their own profiles and requests. The system implements method-level security with @PreAuthorize annotations, row-level security logic to restrict data exposure, and secure DTOs to ensure data privacy—making it a robust backend solution for modern enterprise HR operations.
