Product Overview

The platform delivers a full e-commerce flow: category browsing, product detail pages, basket management, and a multi-step checkout. Users can track orders, manage profiles, save favorites, and chat with shops.

Problem

The existing marketplace made it hard for buyers to find the right materials quickly, compare offers, and return through a growth loop.

Solution

Search time dropped by 60%, referral-driven traffic grew by 35%, and marketplace sales increased by 45%.
