This paper presents the functionality of the "Promotezone" application, its architecture and the technologies used. As marketing has become necessary for the survival of any business venture today, companies are forced to look for innovative and creative ways to promote their products in order to stand out from the competition and increase sales. One of the increasingly popular ways in which companies spread awareness of their brand is promotion through social media using the so-called influencer marketing in which companies find influential people to promote their products. The "Promotezone" application serves to connect brands with their potential promoters. It is not always easy for brands (companies) to find relevant promoters in their area, and the "Promotezone" application tries to solve this problem. Also, from another aspect, it can offer new opportunities for promoters. Brands and promoters can search for each other by various categories and locations, as well as communicate with each other via live chat and save other users in their lists of collaborators. The application was developed using technologies Vue JS, which is a frontend development framework for JavaScript, Firebase (Google's application development platform that handles the entire backend part of the application) and SASS (CSS preprocessor) for layout editing.
