OUR CONTRIBUTION

BUILT WITH

01The challenge

A real problem
worth solving.

The automotive parts market needed a coordinated platform connecting customers, wholesale buyers, sellers, delivery operations, and administrators, handling a complexity that ordinary e-commerce systems rarely address: explicit compatibility between automotive parts and vehicles, multi-role workflows, and server-enforced commercial rules.

Our role

Full-stack developer: built the Flutter mobile commerce application, server-side business logic, and a dedicated Next.js administration portal with SSR authentication.

02The solution

The details that
make the difference.

Multi-Sided Marketplace

Coordinates five independent roles (customers, wholesale buyers, sellers, delivery partners, and administrators), each with their own flows and permissions.

Server-Enforced Commerce

Pricing, discounts, commissions, inventory locking and checkout are calculated server-side rather than trusted to the client application.

Vehicle Compatibility

Parts are explicitly linked to vehicle makes, models, and years, allowing customers to search by vehicle rather than part name alone.

Dedicated Admin Portal

Separate Next.js application with SSR authentication for user reviews, product moderation, order management, and operational control.

Trilingual Support

Full Arabic, English, and Hebrew interfaces with proper RTL rendering throughout the application.
