MERN-Blockchain Supply Chain Tracker

We are looking for an experienced developer to build a mini supply chain tracking system using the MERN stack integrated with blockchain technology.

The system will allow us to track products through different stages of the supply chain, with key events securely recorded on the blockchain to ensure data integrity and transparency.

Key requirements:

MERN stack web application (React, Node.js, Express, MongoDB)

Simple blockchain integration (Ethereum / Polygon / BSC)

Record product lifecycle events on the blockchain

QR code generation for product tracking

Admin dashboard to manage products and stages

Wallet integration (MetaMask) for blockchain interactions

This project is intended as a lightweight MVP, focusing on core functionality rather than complex features. Clean code, basic UI, and clear documentation are expected.
