Education

Phase I

Osnovna šola Videm

This was where curiosity first took shape through computers, problem-solving, and the first real drive to understand how technology works.

Early Curiosity

Phase II

Srednja elektro in računalniška šola Ptuj

Technical high school gave that curiosity structure through programming, electronics, engineering logic, and the discipline of building real projects.

Technical Foundation

Phase III

Fakulteta za informacijske študije Novo mesto

The next chapter is focused on scale, depth, and long-term growth in computer science, building on practical experience in software systems and AI.
