"We're scaling fast (startup, DeFi, enterprise) and infra has to keep up."

Same platform pattern at both ends of the scale: a DeFi startup where I set up everything from the first EKS cluster, and a 200-person FinTech with 100+ microservices. Self-service CI/CD, GitOps, and observability from day one, so infra grows with the product instead of blocking it.
