Ecom website Full stack

I almost got scammed into MLM scheme but see that their website is kinda sleek so I decide to make a full stack ecom website with MERN

Demo Link: https://ecom-kzus.onrender.com/

The website has authentication with sign up, verification and log in. I am using mailtrap to send email but I do not own any domain so it can only send it to my own email which explain the "show verification code" button. Here video of it in action and youtube video link: https://youtu.be/xdgS4dBHpOY

The buyer can edit personal info, add item to cart, I do not make payment function cause this is demo site and I do not know how to test it without selling anything. All transaction are record in server and can be retrieve

Demo video of that and youtube link: https://youtu.be/y-NH0rKZtys

Seller can add new product, edit them or delete them. Demo video and youtube link: https://youtu.be/d8CC_TDBN4c

Doing full stack solo took more time than I expected so there is a lot of improvement I have not had time to do and here is the checklist

• Make it responsive
• Add forgot email and reset password, I can already edit password in backend and have the email template ready I just have not had time to implement it in front end
• Give seller more option to customize shop: change colour scheme, change banner, seller can actually change profile image but that did not save it in back end just yet
• Improve stylling, some stylling like the sign up or log in page look a little bit rough cause I just rush through briefly
• It is a long shot but may be add payement with Stripe
