Yeah I've kinda been that guy. Went from university straight into a green field project that allowed me to grow very fast and I was smart and competent enough to handle it. I knew the project inside and out and everyone liked me. They billed me out at $250 and paid me $40. So I switched jobs after 1.5yrs for a 40% raise. Then the same thing happened, so after 1yr I got another job, also through a guy I had worked with who had seen I was good, for another 15% raise. It's funny how a company can get hung up on relative pay-raises instead of considering actual value added.
