3. I was Arbuckle Leadership Fellow, one of sixty-eight selected by competitive process out of class of 398 – responsible for executing Stanford GSB's core leadership training program.

How I like to work with people As a Cofounder

I am equipped with solid hybrid knowledge from my CS and MBA majors plus real world global experience in both technology development and commercialization. At Yahoo!, I led a cross-functional team (product marketing management, product management, product design, and engineering) of 100 people located globally and won Yahoo! superstar award, the highest award bestow on outstanding employees in Yahoo!

I hope my cofounder will be my technology wingman who can develop sustainable technology solutions based on the markets I've identified and the prototypes I've built.
