Dear Employer,
Wordpress is CMS and it can be extended to ecommerce site by adding a plugin called woo commerce.
If we want Shopify to be used, we have to use Shopify from beginning.
We can work on Wordpress, Woo Commerce, Magento, Opencart, Shopify, Joomla, Virtuemart and core php as well.
Please allow me to discuss in details so I can understand more clearly and project can be taken forward.
You can check my work and reviews on my profile page. if you need links to my work, I can show them as well.
Looking forward to have an opportunity to work with you.
Thank You.
