I was born in Bosnia, but grew up in Serbia. I grew up with learning English together with Serbian language, so I can say for myself that my knowledge of English is excellent.
Spelling goes very good for me, and translation other than literal. With understanding, not just knowledge, I can translate everything from English to Serbian. And not just words, I translate meaning.
I will translate a test job of 500-1000 words for free. Perfect way of proving my knowledge.
