• Role-based access control (Employee, Manager, Admin)
• Software listing and creation (Admin only)
• Access request submission (Employee)
• Access request approval/rejection (Manager)

• Backend: Node.js, Express.js, TypeORM
• Frontend: React, React Router, Axios
• Database: PostgreSQL
• Authentication: JWT, bcrypt
• Other tools: dotenv, nodemon
