Build Shopify website

Need to develop high-end and modern e-Commerce website using Shopify. We will provide the website design, but the website needs to be fully mobile responsive, optimized for speed on both desktop and mobile. Developer/team also needs to be experienced in implementing high-design and UX, including sleek custom page transitions, movements and subtle animations/movements to deliver a very high-end user experience. If your portfolio does not include high caliber design and performance implementations, please do not reply as your bid will not be considered. And only reply if your or the person/team you are tasking to deliver the development work are same as the ones who did the work on the portfolio you are sharing.
