Hi, I'm Daniel. Here's are some of my interest: programming, iOS dev, video production, audio processing, web dev/design, graphics design, photography, 3d modeling & environment creation (Cycles, ftw!), game dev, physics, history, calculus, languages, Bible, bass guitar, music theory, and who can forget about good ol' Stack Exchange!

I was born in the US, but have spent most of my life traveling, I've lived on 3 continents so far. Working and waiting for the Savior.
