There's a Python script in my room that trades for me while I'm at school. Right now it's either making money or losing it, and I won't really know until the close.
That's most of what I do — I build things that keep running when I'm not paying attention. A lot of it is trading: equities, options, two brokers across two countries, the whole stack held together by one tmux session that's been alive longer than it has any right to be. Sometimes I'll go work on a web project for a while when I get tired of watching terminal output scroll past.
I'm 18, headed to McGill this September to study Economics (Arts). I picked econ because what I actually find interesting is how markets work. Coding came after that, mostly out of necessity — you can only do so much by hand before you start wishing the computer would handle it for you.
If you're working on something interesting — a problem you can't quite crack, an idea that needs a second person to look at it, anything you'd rather not do alone — I'd love to hear about it. I'm pretty much always around for that kind of thing.
