The aim of the research described in this article is to develop and implement an educational portal that enables students to acquire additional knowledge and skills by studying the process of creating electronic resources in the educational field. The portal addresses the current demands of digital learning and provides access to supplementary educational opportunities. The article discusses software development methods, the selection of an optimal environment for application creation, and the key stages of the development process. The focus of the research is on creating a supplementary education portal, emphasizing the use of object-oriented programming (OOP) methods, web technologies, web programming, and electronic educational resource creation techniques. As a result of the research, technologies such as PHP, MySQL, and JavaScript were chosen, leading to the successful implementation of the application. An analysis of existing educational portals, such as BilimLand and Daryn Online, was conducted. The outcome of the work was the creation of a functional educational portal that allows students to effectively gain additional knowledge, meeting modern requirements. The portal offers interactive tools available to users and adapts to individual educational needs.
