Just curious, but what type of programming do you do for your investment bank? I've been programming for 30 years now, have done c/c++, Java, reverse engineering, have security clearance, etc but seem to have maxed-out at 130k. I don't know that I've ever seen a job like yours advertised, much less one that pays so well. Can you share what type of programming you do, and how you got into it?
