Projects

I'm a co-founder of the DMOJ, an open-source online programming contest platform.
I also maintain a bunch of projects on my Github profile.

I've worked on many dozens of projects over the years, so I've created this page in an attempt to catalog at least some of them.

DMOJ: Modern Online Judge
