About me

My name is Dio Phung and I am an engineer, a programmer, a builder, husband to a lovely wife, and father of a wonderful boy.

Over the last 2 decades, I have been leading teams to build large and scalable platforms and products for millions of users.

Currently, I am at DocuSign as Senior Engineering Manager  (San Francisco) with a mission to help make our Agreement Cloud a better platform for 180M+ users.

My area of interests include high-scalability and large distributed systems, Internet-scale system architecture, disruptive technologies, human-computer interaction, and the revolution of Artificial Intelligence.

What gets me out of bed is the chance to work with brilliant talents who do not just care deeply about their works but also care about other people. I’m truly gratuitous to work with these amazing people and I’m lucky to have some of them as my mentors.


Outside of work, I’m actively involved with VNPN (Vietnamese Professional Network) to give back and pay it forward by helping young talents to grow their career in Silicon Valley. It’s a deeply meaningful experience for me personally. At the same time, I enjoy being part of the PlatoHQ network where I can meet and learn from engineering leaders in the industry.

In addition, I’m also working on a project which will disrupt we search for knowledge in everyday life (grab a coffee with me to chat).

Last but not least, I am a competitive badminton player. I used to train weekly for men-single and men-double tournament so if you are into badminton in Bay Area, CA – welcome to join me in a game of badminton like this one.
