Hello,
My name is Jarek, and I am from Poland. I speak English for 10 years actually, so I know it very well.
I have done two translation on freelancer so far, and both has been written in a hard technical language, however the principals were satisfied by my work.
I could write many words to describe me and how I work, but I would rather show you. If you are interested in, please let me know in a private message so we can discuss the details.
Regards
