I am a native US English speaker who offers professional proofreading services. I have an excellent eye for errors, including grammar, punctuation, spelling, and formatting.
I generally use the Chicago Manual of Style and the Merriam-Webster dictionary as my main references for proofreading unless you have another preference. I can also work with a custom or house style guide.
I have experience using Microsoft Word's Track Changes feature and Google Docs Suggesting function, both of which are excellent tools for proofreading. I can also annotate PDFs if that is your preferred method to receive changes.
I would love to help you present the best version of your content!
