The aim of this paper is to create a software solution or a web platform that will enable private individuals to sell and buy real estate without intermediary agencies, and to explain algorithms through the work of the web platform and compare them with already existing commercial algorithms. The purpose of the web platform is to allow the user to play the role of buyer or seller, depending on whether he wants to post an ad or search and filter ads according to certain criteria. In order to make it easier for the user to search for ads, we have enabled him to display ads on the home page and the filtering page that might be of interest to him according to the categories of ads that the user searched for. Display of ads can be filtered using user input by county, city, categories, specific characteristics of the selected category, and by price range. The registered user has the option of adding a new ad, updating and deleting it. HTML, CSS and React were used to create the graphic interface, and PHP programming language, mySQL database and WAMP server were used on the server side.
