Dreaming of two cats, a home with a good view, and a happy life writing code from it.
Hi, I'm Junyeong Song.
I have no doubt that AI will do a great deal to make that dream real — which is
most of why I find it worth building.
Outside of that, I read, take walks, listen to music, and play with cats.
I'm drawn to perfume, and to everything beautiful in the world.
