Edit: Let me clarify - not saying that Eastern European programmers are better or worse but the living costs are obviously lower in Eastern Europe than say Western Europe.
I'm working in Hungary as a software engineer, and get about 10$/hour (although I have only 5 years of experience in development). Also, I get more than most of my peers from the university, so it's not that low because I'm a shitty developer :).
With this salary, I'm a very well paid employee compared to others in the country, it's about 3 times more than the average salary.
Not necessary. I'm from Georgia, eastern Europe. I was astonished during my recent visit in Berlin of how cheap it is, especially groceries/food, clothes, toys, etc...
I was also comparing prices in San Diego, California, and it was quite on par with Georgia.
The main reason eastern Europe appears cheap is the human labour - people are just used to low income...
US west coast prices are terrifyingly similar to prices in the Baltic States(unless you're living in a metropolis such as NYC).
Something to remember: It doesn't matter that you're from Ukraine. It matters where the company you work remotely for is stationed. If you find a company in the US or western EU willing to hire you, you can probably ask for their domestic market rates :)
Full time job is OK, but if it'll suit my salary requirements. For now i'm, ok with my current job. But want to move forward.
I mean, I want to learn new techs by part-time job, and then move to full-time.
Don't let this guy to discourage you. Millions of non-native speakers successfully work for American companies although they don't have perfect grammar and spelling.
Look at it from the other side. Who would want to hire someone remotely and part time so they can learn a new stack? If someone is willing to hire both a part time and remote worker, they will want an experienced dev who can bring value right away.
I learned Django / Python on the job (coming from Perl).
My colleague was always ranting about how much better Python was than Perl. Having inherited her code, I was writing far better code while learning Python than she was after doing a PhD in bioinformatics (~4 years?).
