I am a native English speaker from the US and have written award-winning research papers. I offer my editing services for jobs that require extensive grammatical help. I also make stylistic changes so that your work will look like it was written by a native English speaker. When I see repeated mistakes, I offer a short grammatical explanation to help improve your English. I use “track changes” in Word so that you can see the changes I have made.
