Full Stack Of Nested Loops

When someone asks if you're a "full stack" developer and you show them your scientific computing code with nested loops six levels deep. That's not what "full stack" means, but hey, the stack trace when this bad boy crashes will definitely be full! Those nested do loops are giving me anxiety just looking at them. The complexity is through the roof with all those orbital mesh calculations. Who needs clean architecture when you can just nest another loop and call it a day? The person who has to maintain this monstrosity is probably updating their resume right now.
