I have an incredible amount of experience with editing and proofreading rhetoric. I've taken several classes in analyzing fictional and non-fictional literary works, both formal (academic essays, articles, book excerpt, etc.) and informal (personal essays, op-eds, poetry, etc).
I can rewrite works for more eloquence, personality, or tone. I am also comfortable fixing awkward phrasing, helping the flow of certain ideas, and putting into words what someone may find hard to articulate or explain.
