About Me

Hi! My name is Xin-Xin. Or maybe you know me as Dong Fang Wang. I graduated from Computer Science at the University of Waterloo in 2020 and am currently a full-time Software Engineer at Stripe in San Francisco. I do lots of different things. Here are some of the things I've posted on this site:

Programming - In the code section, I post links to various programs I wrote. Most of them are math related. There is a program for factoring integers, one that converts fractions to decimals and shows the repeated digits, a four-in-one page about continued fractions, and an arbitrary precision complex number calculator.

Math - I love solving math problems, so in the math section, you can find derivations of formulas and identities, and interesting problems I've solved.

Music - I love singing and playing piano. When I feel like it, I also do composing, transcribing, and arranging. In the music section, you can find out when and where I will be performing, listen to recordings of my playing, and download my compositions and transcriptions.
