My portfolio consists of Teps and Toeic test modules that I wrote for Seoul National University. In addition, I also did some Toefl Review materials for an American academic writer. My most recent work was assisting a Korean writer in developing Business and Travel books in English for the Korean book market. Other related work experiences include editing and proof-reading academic papers for Korean and Chinese students at De La Salle Taft and Ateneo De Manila. I have also written webcontent, blogs, informationals, travel articles, and e-learning modules on contract for several companies in the US, India, Canada, and Australia.
