This thesis covers full-stack development of an automobile marketplace website, describing everything both on theoretical and implementational level. It explains not only what technologies were selected, but also why were they chosen and how they help develop different features of the website. These features include components such as: Authorization and authentication, listing creation, bidding system and many others. This work also focuses on design of the structure and layout of the website and following of user experience design principles. Even though focus on the design isn't as big as on the technical development, websites still need to be thoughtfully designed along with being technologically developed.
