Jaja ID
Web Dashboard System for an innovative digital marketplace. Offers smart cart management, independent seller inventory control, and multi-courier shipping calculators.
Project Overview
Jaja ID is a local e-commerce marketplace ecosystem aiming to facilitate buy-and-sell transactions by simplifying shipping cost estimation. The system features a self-serve merchant dashboard (seller center) that eases product management, order tracking, and live shipping cost calculations from various courier partners. With an integrated backend system, Jaja ID connects thousands of merchants with retail buyers using a flexible and secure shopping cart architecture.
