Inventory Management System
An full-stack MERN based application to manage Inventory
📖 Overview
This is a robust and scalable Inventory Management System built with the MERN stack (MongoDB, Express, React, Node.js), designed to streamline warehouse operations, product tracking, supplier management, and staff roles.
It provides an admin dashboard to control inventory lifecycle end-to-end, while allowing staff members limited access to manage stock updates. The system emphasizes role-based access, intuitive UI, responsive mobile-first design, and clean architecture with modular components.
🧠 Why I Built It
Inventory systems are the heartbeat of any retail, warehouse, or e-commerce business. I wanted to build a real-world, production-grade solution that could handle everything from stock alerts to supplier records—fully aligned with how enterprise-level tools work. This also helped me solidify my understanding of REST APIs, component-driven frontend development, and practical database modeling.
