Wiktor, I can proofread, and edit 15000 words which will target & correct errors to improve overall readability. I'm a Native-English speaker. With over 9 years of experience, I have superb spelling, grammar, and punctuation skills. I am trained to check for word choice, sentence structure, verb tense, etc. And I have proofread hundreds of reports, e-books, articles, websites, etc.
I can start right now. Just give me a message.
