I have experience in proofreading student work over several courses I have studied over the last 3 years. I spent 2.5 years proofreading and editing ~18000 words in the Finance sector over a few hours and it had to be perfect or our business would fail and our reputation would be shot, so perfect it was. The power of proofreading peer and even employer work before submitting. I also speak around 20 languages at a basic level and am familiar with a number of writing style guides- AP, APA, Chicago etc. I have also edited a novel at a rate of one Chapter per day.
