About Me

Making software is part of who I am, not just what I do—it's in my blood. I get the same kind of thrill from contemplating an elegant design that I've seen others get when tasting a fine wine.

I'm a generalist software engineer with experience as an entrepreneur in Silicon Valley and I'm more than just a coder: my two years of management training and strong communication skills make me excellent at bridging business requirements with modern technology. I've got a degree in Electrical Engineering and Computer Science from U. C. Berkeley and I'm comfortable at all levels of the software development stack.


I am a generalist but lately I've enjoyed developing applications in Node.js using test driven development with Docker containers. You can read my thoughts about the Meteor framework for creating single-page applications.

Open Source

I have created open source projects on GitHub, including:


Bachelor of Science degree in Electrical Engineering and Computer Science
University of California at Berkeley, 1994

My passion is software but I also studied electrical engineering so I can go all the way down to the metal when necessary.

Self-Directed and Effective on a Team

For three years I coached people one-on-one on how to improve their personal productivity and I practice meditation to keep my mind sharp.

I am also interested in how to deliver results effectively on a team so I spent two years studying the science of managing promises in the Generative Leadership Program of The Institute for Generative Leadership.


profile for David Braun at Stack Overflow, Q&A for professional and enthusiast programmers I answer questions about software engineering on Stack Overflow where I'm in the top 10% of answerers for questions about Node.js and in the top 14% overall.

I wrote the (now outdated) Disk Encryption HOWTO for The Linux Documentation Project.

I love to travel and have an opinion on everything.
