Need to develop an e-Commerce website for a high-end electronic consumer product using Shopify. We will provide the custom design, but the website needs to be: - fully mobile responsive - optimized for speed on both desktop and mobile. - developed by a Developer experienced in implementing a high-end design concept and UX, including sleek custom page transitions, movements and subtle animations/movements to deliver a premium user experience IMPORTANT: - If your portfolio does not include high-caliber design and performance implementations, please do not reply as your bid will not be considered. - In your message, ONLY provide examples of custom Shopify work you did that fit the requirements noted above. I DO NOT want to filter through work that is not relevant to this posting. - Lastly, only reply if your or the person/team you are tasking to deliver the development work are the same as the ones who did the work on the portfolio you are sharing.
