Nathan Ko

Intro

Hi, I’m Nathan. I’ve always been drawn to crunching numbers, whether that meant problem-solving, spotting patterns, or finding better ways to approach a challenge. That curiosity first turned into action in Grade 12, when I co-founded a tutoring business with a partner as a way to share my love for math with younger students. Over nine months, we grew it to 17 students, and I found myself enjoying not just the teaching, but the process of building something from the ground up.

Around the same time, that interest in building began to shift toward programming. I started exploring how software could be used to create useful tools and automate tedious tasks, which eventually led to a summer internship at CYC Motor, an engineering startup. There, I helped build and train a retrieval-augmented customer service chatbot for their company, giving me my first real exposure to applying technical skills in a real-world setting. I’m now a 1B Honours Mathematics student, strengthening my computer science fundamentals and continuing to build projects that sit at the intersection of finance, data, and software.
