Worked on the getoutreach/stencil-golang repository to streamline AWS IAM role management by removing KIAM functionality and migrating to IRSA. This involved disabling KIAM by default, eliminating related code and tests, and adopting IRSA-based access control to align with AWS best practices. The migration was implemented using Go and Jsonnet, with a focus on maintaining security and feature parity throughout the process. All changes were validated through existing CI pipelines to ensure compatibility and operational stability. This update reduced maintenance overhead, minimized operational risk, and modernized the repository’s approach to cloud infrastructure and DevOps workflows using Kubernetes and AWS.
