I speak Korean as the mother tongue. I'm also fluent in English as well as in Japanese, both spoken and written (TOEIC 990, JLPT 1). I lived in the States for a year when I was 9 years old and have been using the language since then. I was in Japan for 10 years, doing graduate studies and working in a Japanese company. I also have excellent understandings in technical terminologies especially in computer networking industry.
