It's [zəŋhoan],
but you can call me David.

This used to be me, but now I'm old.
Anyways, I like solving really hard problems.

I also like to tell stories.
Here's a short video I shot during my training in the Army. I got a medal for it. (For real)

Please excuse the potato camera.
I problem-solve (even in my off time) at the bouldering gym, with a diverse, collaborative community of friendly climbers.
