I've a long-standing background in English, not only is it my native language, I've also taken multiple college English courses, sat through many a lecture on the topic, spoke with scholars and experts alike, I've come to realize that articulation is key in guiding the reader to an understanding point. I've edited purely in non-professional scenarios for colleagues, however I have been recommended by many for that reason. I'm new to this site, but I promise you will not regret hiring me for this project. Articulation, accuracy, punctuality, consistency, drive and determination make for the perfect candidate - in me.
