San Francisco Bay Area
I taught myself programming since I was 12. Started a startup that went viral while I was studying in university for my CS master degree, built everything by my own from ground up. Later joined startups at San Francisco, made tremendous amount of contributions to the companies. It has been more than a decade I dedicated in software development. I can pick up most of software technology in no time, dive deeper as if needed to. What I did was something like from fine tuning iPhone app UI down to pixel level with UIKit dynamic animation to designing and implementing highly scaleable real-time streaming audio cluster to improving credit card secure data vault and reduce its PCI scope.
