Hello, I am MD. SAYEED, a graphic and web designer with 8 years of experience. I have worked on many projects similar to yours and have expertise in creating an integration between Shopify Basic Plan and Rapnet or a custom vendor with specific features and functionalities.
I understand your requirement of creating a page to show products from the Shopify store with filters for Price, Diamond Shape, Diamond Style, and Metal Type. Additionally, 0% APR Interest-free credit available should be shown on page load. Additionally, the products should be shown with banners in the middle which can be customized from the backend. Finally customer can set budget for the diamonds from admin section.
I believe I am the best fit for this project due to my extensive knowledge of Shopify Basic Plan and Rapnet API integration. Please let me know if there is any other information or step that I can take to better understand your project needs? Thank you!
