At university, I studied a wide range of subjects related to web development and digital product design. As part of my studies, I learnt the fundamentals of object-oriented programming (OOP), the principles of computer systems and networks, as well as the mathematical and physical foundations of information technology.

Particular emphasis was placed on IT infrastructure design, the development and optimisation of web technologies, and working with databases and SQL. I studied the principles of web programming, including the creation of dynamic applications and the interaction between client-side and server-side components.

I also gained knowledge in the field of user interface and user experience (UI/UX) design, which enabled me to take into account the convenience and effectiveness of user interaction with the product when developing web solutions.
