Is it realistic for a fresh graduate (with a masters) in Informatics and Computing Engineering from Portugal to go straight to NYC and be able to live alone (as in not sharing rooms) and actually have some money saved by the end of the year?

I would absolutely love to experience NY, since I'm a passionate web developer.. There's so many companies in this field over there that I feel that my career would grow so much faster than if I stay here in Europe (at least in Portugal).

I would personally prefer NY over SF since it's way closer to "home".

Any thoughts on actually being able to financially live in NYC as a fresh grad?
