A full-stack HR platform I designed and built for a company running its entire payroll on manual spreadsheets — slow, error-prone, and impossible to audit. The goal was one accurate, role-based system to manage attendance, payroll, and reporting in a single place.

I developed the complete stack: a Laravel 11 REST API and a React single-page app, with separate access levels for admins, managers, and staff. Key modules include a daily attendance grid, an automated payroll engine (overtime, deductions, advances, net pay), PDF payslips, staff loans, a security-fund ledger, bank-account management, CSV exports, and a full audit trail with before/after history.

The toughest challenge was payroll accuracy. A naive overtime sum overpaid employees, so I built a net-overtime engine where daily shortfalls offset extra hours, and centralized every rule in a dedicated service layer for consistency and easy testing.

I also handled live deployment with CI/CD and built-in privacy safeguards — masked salaries, protected routes, and instant lockout of deactivated users.

The result: a fast, reliable system that turns recorded attendance into accurate monthly payroll in just a few clicks.
