Columbia University Math Tutor

Stefan J.

I am a graduate student at Columbia University studying Financial Engineering, with a strong academic background in mathematics, statistics, and analytical problem-solving. I previously completed my undergraduate degree in Operations Research at Columbia, where I built a rigorous foundation in calculus, linear algebra, probability, optimization, and data analysis. My academic training emphasizes not just arriving at the correct answer, but understanding why methods work and how to apply them flexibly to new problems. This perspective strongly shapes the way I tutor.

My interest and success in quantitative thinking began early. Growing up, I competed extensively in national mathematics competitions, qualifying for the AIME through the AMC 12 and earning a top-three team ranking in New York State through MATHCOUNTS. In parallel, I was deeply involved in competitive chess for over a decade, during which I ranked among the top ten players in the country and competed as part of the first-place national team for three consecutive years. These experiences trained me to think strategically, recognize patterns, and remain calm when working through complex problems, all skills that continue to inform both my academic work and my approach to teaching.

My goal as a tutor is to help students gain confidence while mastering the material. Many students I work with initially feel intimidated by math or technical subjects. I focus on creating a supportive environment where questions are encouraged and mistakes are viewed as part of the learning process. By reinforcing fundamentals and developing strong problem-solving habits, I aim to help students not only succeed academically but also feel more comfortable and self-assured in their abilities long after our sessions end.
