In my current gaming software testing role, I analyze RNG results and evaluate electronic games for fairness, integrity, and expected behaviour. I create and adapt game logic and mechanics, validate game behaviour through simulations, and review source code for technical correctness and compliance alignment.

At Polytechnic University of Tirana, I conduct Ph.D. research applying machine learning to data analysis and text classification, and author and co-author research papers. I also bring over three years of teaching experience in statistics, mathematical analysis, and data processing.
