I have 10 years of experience writing and reviewing successful scientific papers and project proposals in English, in several areas of computer science and engineering in general. I can help correct your paper, both in terms of language (syntax, grammar, expressions...) and contents. Typical rates per 500 words are: $10 with a 5-day turnaround; $12.5 with a 2-day turnaround; and $15 with an express 1-day turnaround. Faster rates can be agreed upon if needed.
