BETA website for a nutrition subscription service

We require the candidate to possess the skills necessary to design and develop a BETA website for a nutrition subscription box website that is targeting the endurance sports community. This website will differ slightly from the "traditional" subscription box service, in that the website will automatically track users' consumption. So rather than billing customers periodically, customers will be billed only when new boxes are shipped based upon their consumption. We require the design and development of a 4-5 page BETA website. The pages of the website are as follows; homepage, login/signup page, product listing page, checkout page, my account page. A comprehensive list of features and functionality are provided in our PRD. The candidate should possess strong web development skills and be comfortable working with and integrating different APIs. Previous experience with fitness tracking APIs is a plus. The ideal candidate will also have previous web design experience, with a good understanding of UI and UX principals. Previous experience with Responsive Web Design is also desired. A thorough understanding of ecommerce platforms, payment gateways, and payment processors is integral. We expect frequent communication and collaboration throughout the engagement and the candidate should have strong communication skills. We have a comprehensive product requirements document that will be reviewed with candidates during interview stages.
