Charles (Sáng) Lee

Computer Science, UC Berkeley, 2006
Co-Founder & Instructor

I graduated with a degree in Computer Science from UC Berkeley in 2006, and have 10+ years of being a software engineer in Silicon Valley.

I've worked at three startups, all of which had successful exits. I was one of the first engineers at Luvocracy, a social e-commerce company which was acquired by after raising $11 million in funding from Kleiner Perkins. I was also the second engineer hired at venture-backed local recommendations startup GemShare, which was acquired by the social networking site NextDoor in early 2015.

The past year I've been working with startups CodePath and Bloc teaching iOS, Ruby on Rails, Javascript, and Java.

Computer Science, Yale, 2010
Co-Founder & Instructor

I was born and grew up in Vietnam, and have spent 15 years mostly abroad in Singapore, the US and China

I studied Computer Science at Yale university, started two funded startups and went through two accelerator programs, Techstars in the US and Chinaccelerator in China. When I'm not serious (49% of the time), I like music, dancing and drinking in no particular order. Sleeping is overrated.

2016 has been a great year for both CoderSchool and myself. Primarily thanks to the work at CoderSchool, I was awarded Developer of The Year in both Vietnam and ASEAN startup awards.

Co-Founder & Business Development

For the past 10 years I’ve been a startup entrepreneur with ventures ranging across non-profit education, commercial real estate development, Music, and Internet Technology. Most recently, I worked with CodePath designing and implementing technical training programs at Walmart.

I pursued undergraduate and masters degrees at New York University where I studied innovation, behavioral economics, and classical literature.

I choose to spend my time where I’m most inspired. For my whole life, this has been the intersection of opportunity, passion, and purpose. I enjoy growing ideas, thoughtful intention, building relationships, and systems based thinking.
