01 — About
I'm a Software Engineer who loves building things, exploring the world, and capturing it through a camera lens. When I'm not coding, I'm usually reading, playing basketball or football, or catching up on Attack on Titan.
I build things that
look as good as they work.
The engineer
I ship end-to-end and own the whole stack.
The researcher
ML and data science.
The photographer
I shoot on the side. It's why this portfolio looks like a darkroom.
