I'm developing Android application since 2011. I'm currently developing personal fund management service 'Banksalad' at Rainist, South Korea. I like to share my knowledge with presentations, blogs and etc. I'm also interested in developer community so participating organizers of Android conference 'Droid Knights' in South Korea. I have experience of startup EXIT even after foundation and failure, and still challenging in a new startup, Rainist. I'm interested in creating user values with collaboration and business, besides development. I think development is just one of the tools for that values. I want to be a person who enjoys life and knows the world rather than who is just good at development. So, I like to meet new people and challenge various hobbies such as travel, festival, soccer, dance, game, animation, etc.
