Yes, you're grossly underpaid. You're doing 100% the right thing by building up a portfolio. That said, it would be a mistake to think that you can fix this problem with code alone. While a portfolio can "do the talking" to get you in the door, you still have to communicate with your coworkers once you're there. I'd second others opinions to talk to your GP, tell him/her that your speech impediment is affecting your career. Put just as much effort into working with a medical professional as you did/are with your portfolio, and over time you'll have no trouble earning what you're obviously worth. [EDIT: Also, let your employer know that you're doing these things. Chances are you're more vital to them than you realize, and all of this will help you get that raise. But if you do get it, don't let that placate you. Keep improving yourself.] [Second edit; I confused this with a Show HN post I was reading at the same time, sorry. Sentiment is the same, however.]
