Hi! I’m Roger!
I’ve used many handles online, but they typically follow the regex /kirito[\._]?feng/.

I am a fourth year Mathematics and Computer Science student at the University of Waterloo.

When not doing homework, you might find me working on the DMOJ: Modern Online Judge, Canada’s largest online judge for computer science contests, as either an administrator or a developer.

Other hobbies I have include reading and translating the Chinese IOI team selection papers, LaTeX typesetting, and origami.

If you are interested in what I have to say about these topics, you can check out my blog. Other things I have worked on can be found on my projects page.

Finally, my LaTeX typesetting skills, in the form of my résumé, are showcased here.
