I'm a doctor in the field of computer science and taught in Korea Air Force Academy for more than 15 years as an active duty officer. After discharged from Korea Air Force in 2012, I worked for 7 to 8 companies as a programmer. One of the company was my own company which developed open source parking lot management software in Java and MySQL.

Probably, three most important factors on me are -

1. OsParking (Parking lot management software) source code(80k code lines).
2. Web site of my Company(Open Source Parking, Inc.).
3. My patent on combobox hierarchy selection - abstract at engportal.kipris.or.kr use keyword combo "combobox jongbum". Also a video clip introducing my patent idea is on youtube.
