I am an English native speaker. I've worked as a writer and editor for a long time. I can proofread and copy-edit any piece of writing, including non-fiction and fiction, books, stories, and articles, website content, science papers, standard essays, print documents, pamphlets, reports, and so on, because I have a strong background in grammar, punctuation, sentence structure, and content clarity. I swear I'll never let you down. Thank you very much!
