Old Machine Market is a full-stack web application built to enable users to buy, sell, and manage industrial machinery seamlessly.
The platform provides a professional B2B marketplace for used or new equipment — such as construction machines, manufacturing tools, or agricultural equipment — allowing sellers to list products, buyers to explore listings, and admins to manage the platform efficiently.

It includes user authentication, secure payment and plan-based publishing, photo uploads, and a dynamic React frontend connected to a RESTful Node.js + Express backend with a MySQL database.
