Below is my introduction!
My name is Jung. I am thiry one years old and I am an engineer. I majored in engineering in college, and I have been working at SAMSUNG SDS for about two and a half year now. I am in chagr of
maintaing and adjusting cost estimation system. I like what i do and I think I am pretty lucky for that. I live by myself in Seoul. I move out a year ago becasue of the long and tiring commute to wirk. I feel lonely sometimes but it is really nice to have time for myself when I am tired from work. In my free time, I try ro visit my parents every other week. I like spending time with my family because it relieves stress. I usually hang out with my friends or my family during the weekend. My family and friends are the most important thing in my life.
