Back End Ecommerce Node js

The EcoShop Backend API serves as the complete server-side architecture for an e-commerce platform. It manages all business logic, data persistence, and security concerns, allowing frontend developers to focus entirely on user experience. Built with scalability and maintainability in mind, the system handles thousands of concurrent users with efficient database queries and caching strategies.
