“I don't just write code.
I write solutions.

Hey, I'm
Rainier.

// Self-taught software developer from the Philippines — started with CS50x and CS50P, fell deep into code, and never came back up.

// I care about the full stack: the logic underneath, the interface on top, and the tiny details most people scroll past.

// When I'm not building, I'm learning. When I'm not learning, I'm breaking things on purpose to understand why they work.
