Co-Founder at Presdo
San Francisco Bay Area
I come from computer science research background. My focus areas at UC Berkeley were Artificial Intelligence, Wireless Sensors Network and Computer Graphics.
I deferred my PhD. program from Cornell and worked at LinkedIn. At LinkedIn, I built the LinkedIn Firefox toolbar; I brought in new technology and built a rapid development team; I led and architect the Mobile platform with applications including the WAP application, iPhone app, IBM Lotus integration, and more.
Now I am at Presdo trying to build a product that is fun, powerful, and easy to use.
I build stuffs, I have a lot of energy, and I am not afraid to start from beginning.
