E-Commerce website + Simple CRMS (React)

Hi,

I want an E-Commerce website built in react +anything on the backend

The CRMS Service needs to allow the ADMIN to add new items including:
{item name}
{item description}
{item quantity}
{item weight}
{item price}

How I want the website to look:
Homepage:
-Has a sidebar with categories of the product
-Has items listed
-Has Footer

Login:
username (string)
password (string)
login button
LINK TO REGISTER

register:
username (string)
password (string)
company name (string)
company tax code (gus integration) - https://api.stat.gov.pl/?lang=en
email (email regex)
register button
link to LOGIN

Ability to add items to CART
Cart notification with the number of items
Basket total
ability to purchase (without credit card info)

Checkout page:
Standard checkout with grand total and all items in cart (including their overall weight + quantity)

the filled out checkout form gets sent to a custom email address with all its contents

The images represents a rough skeleton (not design) of how I imagine home // login // register pages to be laid out.

Will provide better skeletons
