ABOUT
Applied Informatics graduate (Bc.) from Constantine the Philosopher University in Nitra, continuing my studies
at Master's level. I enjoy working with data - collecting, cleaning, modelling, and visualising it - with particular
interest in Python-based analysis and working with large datasets. Looking for a part-time student role where I
can apply my skills, learn from experienced colleagues, and contribute to real-world projects.
