A Full-Featured E-Commerce App (Customer + Seller) – Amazon & Noon Style
A modern, production-grade E-Commerce mobile application built with Flutter, supporting both Customer and Seller flows, inspired by platforms like Amazon & Noon. DropZ is designed to demonstrate how a real-world shopping app is engineered: secure payments, biometric verification, scalable architecture, and clean, maintainable code.
This project is built as a professional portfolio showcase, following patterns and practices used in large-scale mobile products.
DropZ simulates a complete online shopping experience — from discovering products to securely paying and contacting support — while focusing heavily on architecture quality, user experience, and security.
The goal is not just to make the app work, but to make it scalable, readable, and production-ready.

- Easy to scale
- Easy to test
- Easy for teams to collaborate
- Avoids massive, tightly coupled codebases
Development follows a feature‑branch workflow:
feature/auth
feature/home
feature/products
feature/cart
feature/checkout
feature/address
feature/reviews-system
feature/profile
feature/settings
feature/support
This mirrors how professional teams manage parallel development.
