I have very unique skills for high-performance, low-latency programming especially in Java and C++. There aren't too many people who go digging through assembly dumps from Hotspot. I've been doing this for about 15 years now. It can be very stressful. I've literally had a day where I lost a million dollars in seconds, but I've also had days where I've made tens of millions in seconds.
I'm a very good programmer. My math skills are pretty good too.
I live in NYC (I've also lived in Chicago). No surprise there. Right now I'm actually taking a pay cut to work at a finance startup. Maybe one day I'll be principle of my own firm. Or at leave a C-level :)
