Developer, Dreamer — Hanoi City
I build things on the web. I think about the cosmos at night.
About
I'm Tung — a full-stack developer with over a decade of building products. I prefer quiet over noise, depth over breadth, and a well-placed line break over a cluttered screen.
When I'm not writing code, I'm reading about the large-scale structure of the universe, working through problems in classical mechanics, or sitting with a philosophical question that has no clean answer. At home, there's my wife and our two kids — they are the reason I try to keep things simple.

I'm not easy to reach — that's intentional.
But if something is worth saying, here's where to say it.
