My name is Jeff Chien (JeffChien@mail.utexas.edu). I'm a student majoring in computer science at the University of Texas at Austin. I enjoy competitive programming in events such as the ACM International Collegiate Programming Contest and know Java fairly well. I've also had experience working with C, C++, and Javascript. Languages I've used very briefly include Perl, Pascal, Haskell, Franz Lisp, LC3 Assembly, NQC, and Visual Basic.
Within computer science, aside from the core classes such as data structures and algorithms, computer systems architecture, and operating systems, I've also taken cryptography and data management. In Spring 2007 I'll be taking programming languages and a more advanced algorithms course. Outside of computer science, I'm very interested in learning Chinese and about my own heritage, and will be taking the fourth semester of the Mandarin language course offered at UT.
Though to many, programming in contests probably doesn't sound like much fun. I can assure you it's not nearly as dull is it sounds. In 2005 I competed in the Association for Computing Machinery (ACM) International Collegiate Programming Contest World Finals in Shanghai, China, receiving an honorable mention. That's as far as my competitions have taken me so far. I've also been able to go to Disney World in Anaheim, California and visit downtown Chicago, Illinois through the American Computer Science League (ACSL) All-Star Competitions. I also led the team that took first place in the University Interscholastic League (UIL) Computer Science competition in 2004. However, success only came with the help of great, talented teammates. I'd also like to thank my high school coach and mentor, Bekki George for introducing me to computer science and competitive programming.
These are some of the older programs I have lying around.
