I graduated from the University of Wisconsin - Madison with degrees in Chemical Engineering and Computer Science, and I am currently working for a global company named Mars as an IT business analyst. I am passionate about teaching maths, physics and computer science. I have extensive experiences in web development work (HTML, CSS, JavaScript, .NET, PHP, and SQL). Language-wise, I am fluent in English, Cantonese and Mandarin Chinese as I was originally from Hong Kong but came to America when I was 15 years old.
