This thesis deals with and describes the process of creating a web application for keeping records of professional practice at faculties. The creation of the aforementioned web application was undertaken due to the current popularity of web applications, but also due to the identified lack of a specific system or application that would allow faculties and students to more easily keep records of professional practice. The web application was built using very current technologies such as PostgreSQL, ASP.NET Core, .NET Core, and React, and Visual Studio 2022 was used to write the code. Web applications consist of several key elements, each of which has its own role and essential part in the functioning and operation of the application. Therefore, the thesis also describes the creation of the backend of the web application, i.e., the database, the web API, the middle layer, and the data access layer, as well as the frontend, which is used to display data and results to end users. As a result, a web application was created to facilitate faculties to keep records of their students' professional practice, and all important parts and elements were implemented and described.
