This bachelor thesis’s task is to create a full-stack web application whose job is to track journeys in the form of a journal. When creating an application, I used the following technologies: HTML, CSS, PHP and MySQL. The application is both interactive and responsive. In this document I will deal with: how to create this application, what technologies are used, possibilities of maintaining this application, application errors, how is the code written, conclusion. Solving the problem of the bachelor thesis leads to personal development in this area of the IT profession. Despite using procedural programming in PHP. The conclusion is reached that it would be better to use a framework. There is nothing particularly wrong with php. The reason for this is that with proper use of the framework, applications become more scalable (or at least they are created faster), some things are also automated, so it is easier to change and maintain things. If avoiding a framework is necessary, then at least object-oriented PHP. Of course, the result (of solving the problem of this bachelor thesis) is still satisfying because this full-stack application does what it was intended to do. Various errors were found in the application, which had a positive effect on development, because it has been learned that one should not give up, sometimes one comes up with a solution for a current problem just by being patient.
