About Me

I go by C0ldSmi1e or Daniel Yu. (Yes, that's a zero and a one in there — I'm pretentious binary-friendly.)

Caffeine-powered code wizard with Cantonese roots. (My ancestors perfected dim sum, I perfect algorithms.)

Currently building AI stuff that hopefully won't take over the world and crypto things that might actually pay for my coffee addiction. Americano is life.

When supposedly taking a break, I'm either competitive programming (furiously typing on a keyboard while glaring at screens and whispering "edge case!"), investing (contemplating how the world works to glimpse the future, not just day-trading like a caffeinated squirrel), swimming (achieving perfect human-fish harmony), cooking (channeling my Cantonese heritage into dishes that taste better than they look), or strumming my guitar (still working on that fourth chord).

Devoted fan of Leo Messi, Max Verstappen, Stephen Curry, Liverpool, Golden State Warriors, Barcelona, Red Bull, and more.

Cluely is still a "cheating" tool that AI answers questions from somewhere hidden behind the screen.
