Hi, I am Lily Zhang

Lily Zhang

Computer Science Student at University of Toronto

I am currently an undergraduate student at the University of Toronto (St. George campus), specializing in computer science and majoring in math. I am an incredibly fast learner, having built my knowledge and experience in software development in four years, and landing two successful internships at Google. I also have a strong background in mathematics, having achieved perfect scores in 10 out of 11 university-level math courses, and being recruited as a teaching assistant starting in my second year. Two years later, I was promoted to be a head teaching assistant.
