Summary

During Business Analytics studies, I acquired technical skills in data analysis and programming. The course prepared to bridge business and IT, translating findings for non-technical audiences. The program emphasized collaborative projects with many presentations. I blend my interest in data science, statistics, and machine learning with a desire to drive change through data-driven decision-making. I enjoy exploring new cultures, am open-minded, adaptable to changing environments, and have substantial experience working in international teams.
