I am a pre-undergrad student currently working as the head back-end developer at Gala, a small social startup. Hope you'll recognize my name on the news some day.
Javascript, specifically node.js is my primary development platform. I am comfortable with a wide range of modern tools, from shell scripting, to babel. C++11 is my main language for competitive programming, where I previously used Java (much slower, I hate garbage collection in languages :/). I use python, java, shell, c++, javascript, and more for personal projects.
I also study pure math and computer science.
