    In the modern world, autonomous technology has largely taken the place of directing structures. An e-commerceewebsite is one thattenables users to buy and sell physicallgoods, services, and digital goods over the internet as opposed to at a physical store. Through an e-commerce website, a business can manage orders, payments, logistics, shipping, anddscustomer service. Our website name is SellPhone. Here any users(buyers) can sell their old phones and users(sellers) can sell their old phones. Our website is a full-stack and responsive website with some good features like searching for category-based products. The front end is built with the javascript framework ReactJS. We designed the website with the CSS framework tailwind. The back end is built with ExpressJS and NodeJs. For the database, we used MongoDB to save all kinds of information. For the user login system, we used Firebase. To secure our APIs we used JWT (JASON WEB TOKEN). Buyers can easily purchase an old used cellphone and pay their payment by using any international card.
