Uncontrolled AWS spend (~$9k/month), no governance, and direct production deploys. I built a FinOps framework (cost allocation, tagging, showback), redesigned autoscaling, and introduced a dedicated dev environment. Result: $9k → $3.5k/month (61% cut), a further $1.8k/month identified, and deployments from 14 min → 1 min 40 sec (88% faster). Stack: AWS, Terraform, GitHub Actions, FinOps tooling.
