Software Engineer
I'm a code nerd obsessed with system design and clean code. I draw boxes and arrows until the architecture makes sense, and refactor for beauty. Still waiting on Marvel to redeem itself through Brand New Day and Doomsday. Ping me at chris@chiristo.dev - let's talk systems, clean code, or even chaos.
