Project Overview
Perinvo Salary Intelligence is a professional web-based Egyptian salary calculator designed to simplify payroll calculations and support clearer compensation decisions.
The application brings together my extensive experience in payroll management, compensation and benefits, statutory deductions and HR digital transformation with practical digital product development.
