I am Alexander, and I will work with you to make sure that it is and they will.
I will hunt down mistakes that might disrupt a reader’s experience and embarrass you. I’ll look for errors of spelling and grammar that software may not catch. I can, if you like, go beyond cleaning your prose to helping you polish it: fighting wordiness, reducing repetitiveness, and suggesting more compelling phrasing.
In short, while no one can promise perfection, I can guide you closer to it.
Whatever I suggest, of course, it always remains up to you to make the final decisions. I am merely your adviser. In some cases, I may not even say what you should do, but simply raise questions. In all cases, my goal is to give you the chance to fix problems before anyone else sees them.
