About Me


I started to study programming since 2010 when I had all grown up. It was a little late. But I had a strong passion for programming and tried hard, so I majored in Computer Engineering. And I have worked on web development projects since 2013 in Seoul. Recently, I work as a freelancer in financial projects. I have tried to do better than the present all the time, and I will.
