Founded in 2015, Le Portier as an online marketplace provides the safest way to shop luxury items especially for pre-loved. Le Portier also has a partnership with a professional company based in the U.S. that has more than 15 years of experience in authenticating luxury brands to authenticate for particular brands and models which are known to have super fakes in the market. One of our challenges in the making their website was focused on the navigation by considering how the customer may have a trouble to find a specific product. Hence, we created filtering system to make it easier for the visitors to discover an item on the website. We also added some features such as checkout process and report of order.
