Hello,
If you check out my portfolio (located on my profile), you will see that I am a highly skilled candidate for this job. I have proofread and edited many diverse writing projects in the last 2 years. I've done such work to improve countless student essays, a book of poetry, a technical article for the University of Guadalajara, and even a partnership proposal between two international companies.
The reason I've done so much diverse work is that I am trying to accumulate as much experience as possible, to better my chances of landing a full-time job at a local company.
If you direct message me, then I can send you a "before" and "after" version of my work (I can't attach anything to this message).
