About me

Dio Phung

I’m a software engineer, builder, maker, and a lifelong learner with a mission to transform lives with technology.

Over the last 15 years, I have been leading teams to build large and scalable platforms and products for millions of users.

Currently, I am at DocuSign in San Francisco, CA as Sr. Engineering Manager, with a mission to make DocuSign Agreement Cloud a better platform for 200M+ users.

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

What gets me out of bed every morning, 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 grateful to work with these amazing people and I’m lucky to have some of them as my mentors.


Mentorship is a deeply meaningful experience for me. That’s why I’m actively involved with Vietnamese Professional Network to help promising talents grow their career in Silicon Valley. I am also part of PlatoHQ network where I learn from other industry leaders, and I worked with the wonderful team at steamforvietnam.org to help with their educational mission.

In addition, I’m working on a platform to democratize the future of A.I. development. I live in the sunny Bay Area, California, feel free to grab a coffee with me to chat.

Last but not least, I am a competitive badminton player. I train weekly so if you are into badminton – join me in a game of badminton like this.
