Good payment engineers focus on business logic rather than performance or clean code. Common antipatterns in payment system designs include relying solely on synchronous responses from PSPs, confusing payments with money transfers, building on a card-first design, using incorrect state machines, and sticking to early database decisions. Addressing these issues can lead to more robust and maintainable payment systems.
