web application

I am looking to develop an e-commerce web application with a shopping cart feature. As I am open to suggestions, I am looking for a freelancer who can create a feature-rich web application that can be used for commercial purposes. The web application should enable users to buy and sell products from an online storefront. The shopping cart should allow customers to add and remove products from their shopping cart, provide payment options, track delivery status, and display the order history. Furthermore, the application should integrate with payment gateways as well as offer other features like product search, promotional codes, customer support, and secure transactions. The web application should also be responsive, user-friendly, and easy to navigate. Finally, I would also like the freelancer to consider user feedback and incorporate improvements to the existing web application.
