ABOUT

About me

My passion in making creative experiences dates back to my high school times. Back then I was maintaining and directing my love towards art into variety of medias whether in non-profit organizations or freelances. I have been proud to be able to help entrepreneurs and local businesses to reach their customers and clientele therefore improving their business significantly.

My professional career in San Francisco starts as a design intern in a marketing agency Btrax and San Francisco International Airport (SFO). Right after I graduated from Academy of Art I got recruited right away with AKQA where I'm proud to be a part in many fun, high profile and award winning projects. After several freelance projects, I worked on an eCommerce project with Charlotte Russe. Then I moved to Meta (Facebook) Small Business Group which I was blessed with many great projects that helps Small Business around the world. Currently I'm working back with Apple within RFSAC as a Frontend Developer to help them build the best high quality devices. It's a jump from sales and marketing to manufacturing, but it has been incredibly fun working with huge amount of data points.

As a Frontend Developer, I love creating online experiences where latest innovation meets creativity to solve problems. I consider myself as a resourceful and knowledgeable entrepreneur, analyst, developer and designer who always hungry with latest innovations and pay homage with core concepts and structures for scaling infrastructure, integrations and compliancy.
