I wrote a basic bootloader shim at 11. It was a crappy 100~ LoC file, held by chopsticks and tutorials. I also wrote a "kernel" that just printed "Hello World!" to VGA. My first experience with coding was at 8, I made a basic bullet hell from a template with GameMaker studio and GML.

And damn, you guys are pretty young!
