Miscellaneous

I’ve been designing mobile experiences before the iPhone was invented, won a Cannes Lion, and even made it into the “Mobile Websites for Dummies” book. Beyond work, I’m a ranked foosball player, have traveled to 30+ countries, and am a proud child of Khmer Rouge survivors. I thrive on challenges and can always find a way around a problem.
