This is a product recommendation system that I built for a hair care company. Visitors answer 10 questions about their hair and then the system recommends hair brushes and shampoos.
There's an admin area where the owners can edit the recommendations and view past answers.
This was built with Linux, Windows, MySQL, these PHP libraries, jQuery, the Google Analytics API, the Shopify API and the zippopotam.us API. The project date is winter 2018/19.
