About
GroundUpCoder is a writing companion to the YouTube channel of the same name. It's where ideas land when they're too long, too written, or too quiet for video — compilers, WebAssembly, low-level programming, the craft of explaining how systems actually work.
Written by Joseph Kim. Most posts are companion essays to videos, but some are their own thing.
