Build Web HR Management System

I need a production-ready, web-based HR Management System that unifies three core areas:

• Time & Attendance – real-time clock-in/out, leave management, overtime tracking, and the ability to record salary advances.
• Payroll Processing – automated calculations tied to the attendance data, statutory deductions, and downloadable payslips.
• Employee Management – smooth onboarding/offboarding workflows, performance reviews, and secure document storage for contracts, IDs, and policies.

Security, role-based access, audit logs, and a responsive interface are must-haves. I’m open on the tech stack as long as it is modern, scalable, and well documented; propose what you do best and outline any frameworks or cloud services you plan to use.

Deliverables will include the full source code in a version-controlled repository, a staging URL for iterative reviews, database schema, API documentation, and deployment assistance to our chosen cloud host. Please share relevant live web apps you have built that demonstrate similar complexity and describe how you would approach each module’s architecture.
