Although I'm not a native speaker, I have a fluent English, as I've been learning and practicing for around 10 years. I am proficient with English grammar and punctuation.
I can write an article on any theme, using all the information that could possibly be found on the topic. I have some experience with wiki articles as I wrote articles for russian Godville wikia, so I have full understanding of the mark-up.
Depending on the size needed, I can write one article in 4-7 days, including the time I need to do some research on the topic.
Regards,
Oksana M.
