We designed and implemented a cloud-native DevOps architecture that consolidated tooling, standardized pipelines, and automated release workflows. AI agents validated configurations, flagged security gaps, and enforced deployment policies in real time. Jenkins, Terraform, and GitHub Actions were orchestrated into a unified delivery system—accelerating throughput while maintaining rigorous controls. Developers now ship faster with confidence, SREs spend less time firefighting, and the bank operates with the agility of a fintech—without sacrificing governance.
