Although I don't have any experience on Freelancer.com, I have lots of academic experience in writing articles in English and blogging in general. I am close to graduating with a BA in American Studies which includes courses such as Rhetoric and Composition, Journalism classes, Academic Writing, Debating, History, Cultural Studies,etc. I can write mid-length (between 500 and 1500 words) articles relatively fast. If I have been provided with the materials needed to write the article or the topic of the article, I can finish it in up to one or two hours. I hope I'll hear back from you!
