My career seems hopping between small and big companies. In April 2004, I joined Fortinet, another start-up. We make real-time antivirus firewall and intrusion prevention systems. After 5 years playing with telephone, I now peek every network packets going through our box.

In 2001, after working at Altigen for two years, I came back to another big company, Cisco Systems, the worldwide leader of Networking equipment makers and the dream of thousand start-ups in Bay Area and around the world. A good thing about big companies is, you can learn and relax at the same time. I wrote software for Cisco Voice Gateway here.

At the beginning of 1999, I joined Altigen Communications, the leading manufacturer of Computer Telephony (CTI) system for small to mid sized businesses, maybe the only one survived. The technology and products are solid, but market and sales didn't fly. The IPO wasn't exciting even at NASDAQ's most red-hot time. From here, I formally stepped into Telecommunication industry.

I worked at Oracle Corporation in 1998, in iFS (Internet File System) Group, the most bragged component of Oracle8i. Most of my colleagues later left Oracle and formed salesforce.com, who survived dotcom crash and became one of the most anticipated IPO during high-tech revival.

I got my Master degree in Computer Science from George Mason University, Fairfax, Virginia in 1998. I was a graduate research assistant of Dr. Mark Pullen at Network and Simulation Lab of Department of Computer Science, School of Information Technology and Engineering (SITE). My research interests are IP multicast and QOS.

I graduated from Tsinghua University, Beijing, China in 1994. My major is physics.
