E-commerce for second hand fashion

This is a fullstack e-commerce application, in progress, built with the MERN stack. I have created the project from skratch, doing UI design, frontend and backend. There is a user and admin login. The admin can add/edit and remove new producta as well as users. It also has an order tracking system. As a payment solution I am using PayPal, and more options will come later in the process.
