I used Excel to evaluate a publicly traded Greek company's historical financial performance under IFRS, calculating liquidity, solvency, and profitability ratios to analyze working capital trends.

As a self-employed Private Mathematics Tutor, I led personalized programs for 10+ students, resulting in an average 30% improvement in standardized test scores over one academic year. I also analyzed student performance to identify learning gaps and develop structured study plans.
I earned a BSc in Mathematics from National and Kapodistrian University of Athens (EKPA) and am currently pursuing the Google Advanced Data Analytics Professional Certificate. I'm developing my SQL, Python, and data visualization skills, with a focus on predictive modeling and actionable business insights.
