Shopify Online Store Development

I'm in search of an experienced Shopify developer to create an online store for the sale of physical products. I require a dynamic shop that is easy for me to maintain, update with new products, and to run promotions.

Key features should include:
- Product search and filtering
- Customer reviews and ratings
- Discount codes and promotions
- The ability for the website to remember customer's shopping baskets
- An integration with payment option, Klarna

If you have proven experience in Shopify development, a keen eye for user-friendly functionalities, and understanding of ecommerce best practices, please bid.

Happy to provide reference websites.
