Customer product filter functionality on Shopify store

Shopify developer required to deliver the following features within a Shopify store. • When logged in, customers will have a ‘My profile’ page where they can define and alter the departments, sizes, brands preferences that they are interested in. • Collection pages will then be filtered by these selections when the customer browses the collection page. • Customers will have the ability to clear all filters to view the all products within the collection they are currently browsing. • Departments will be a subset of the Collection pages in the store (Mens, Womens, Home & Garden, Electricals, Beauty, Child & Toys, Sport & Leisure & Gifts) • Sizes will be all variant options divided into clear sections (e.g. Shoe, Neck, Waist, Chest, Leg) • Brands will be ‘Vendor’ in product admin • Filters are already implemented on the Shopify store using product tags • Because there will be many brands and sizes to filter by, the filter area of collection page will need to be amended to only show a specified number of brands by default, the option to expand to ‘see all’ within the filter box. • Screenshots will be provided for the formatting of all pages. Please only submit a proposal if you have examples of development work on Shopify stores – not just store design and theme work – but actual functionality deployed within the Shopify framework.
