Project Overview
We built a comprehensive enterprise e-commerce ecosystem for a major retail conglomerate operating 15 brands across the Middle East. The platform serves as a unified marketplace connecting 500+ vendors with millions of customers, handling over $50 million in monthly GMV (Gross Merchandise Value).
