And they that be wise shall shine as the brightness of the firmament;and they turn many to righteousness as the stars for ever and ever.

About Me

I'm a Ph.D. student in CS at [UT Austin|http://www.utexas.edu]. I finished B.S. at [Seoul National University|http://cse.snu.ac.kr]. Before I came to UT, I worked at several startup companies for 5 years. My blog has some Linux and programming geek stuffs. I joined USC/ISI East from June 2009, and currently finishing up my dissertation remotely.

Professional Experience

  • Firewall/Router Developement
    • I implemented central control module for firewall/router which supports multiple ADSL lines.
    • This product was sold to Korea Telecom where I could get a chance to experience biggest network infrastructure in Korea.
  • Web application development
    • http://www.iyah.com (No long open. T.T OTL)
    • By the time I was involved, this website used around 10 servers (Frontend Linux(Tomcat), Backend Solaris(Informix)).
  • Digital TV Settop Box development
    • I was involved in this project for very short time. I implemented some of DVB DHP spec using Java.
  • Personal Computer manufacturing
    • I tested various hardware parts, from motherboards, video cards and even cases and boxes.
    • I also had set up the factory and manufacturing process.
