Hi. I´m American, a native English speaker, now living in Brazil. I have many years of experience with proofreading and editing of English texts written by other people. This used to be part of my work, along with writing and translating operations and production reports, correspondence and technical manuals for multinational companies in the oil business. Now I do the same things, mainly for university students and post-graduates who want to publish their academic work in perfect English, as well as some local book publishers, people writing for blogs and sites, etc. I correct grammar, spelling, punctuation, vocabulary (choosing the best words for improving the clarity of communication), flow and readability, repetitions, etc. I use the Track Changes function of Word to show the corrections and comments I make on the text I can give you the best price for my services if you can tell me how many words are in each text (Word shows this number in the lower left-hand corner of the screen), what are the topics of each text and your delivery deadlines. If you´re not in need of urgency, I can give you a better price. Please contact me with these details, and I hope we can work together.
