Hi. I’m CJ. The thing I like to do most is write. I strive to write clear handouts, usable websites, and honest blog posts.

My full name’s Carl Joshua Quines, but you can call me CJ. I’m nineteen, and I’m a freshman at the Massachusetts Institute of Technology.

Here’s my resume, some frequently asked questions, and contact details.

Math

I write handouts on competition math and other math I find interesting. My emphasis is on explaining things clearly and giving intuition, and most of my handouts have pretty light prerequisite knowledge.

I’ve done a little bit of math research from PROMYS, MIT PRIMES, and elsewhere. I’ve coauthored four papers on the arXiv, and they’ve all been on graph theory.

Right now, I help train the Philippine team to the International Mathematical Olympiad. This summer, I will be a counselor for PROMYS, after attending as a student for two years.

Code

I enjoy programming a bunch of miscellaneous projects. A lot of my recent work is web development, with a focus on the front-end. I believe good websites should be easy to use, quick to load, and nice to look at.

I’m actively involved with competitive programming. When I joined contests more often, I went to the International Olympiad in Informatics, and made it to Round 3 of Google Code Jam. Now, most of my work is in organizing the National Olympiad in Informatics – Philippines, writing problems and training material.

Other things

Writing is one of my hobbies. I’m a blogger for the MIT Admissions blogs, where I publish posts on student life around once a week. I collect my favorite posts on my writing page.

I’m in a lot of MIT student groups. Right now, I’m doing a lot of work with the MIT Educational Studies Program; we run educational events for middle and high school students around Boston. I do square dancing and round dancing with Tech Squares, and I’m the president of the Filipino Student Association.

On this website, there’s a FAQ, with questions mostly about studying in the US, and math and programming competitions. I care about design enough to have a colophon.

If you have a question, found a typo, or just want to talk, you should contact me. I read and reply to all emails I get, and I always like it when I get an appreciation message from someone.
