Worked on the entigolabs/entigo-infralib repository to enhance AWS EKS infrastructure automation using Terraform and HCL. Focused on reducing configuration drift by removing unsupported addon configuration values, which simplified module usage and minimized misconfiguration risks. Introduced a conditional enable_efs_csi variable, allowing users to opt-in to EFS CSI driver and IAM role deployment, thereby supporting flexible storage backends in EKS clusters. All changes were clearly documented for traceability and future maintenance. This work improved the maintainability and clarity of the infrastructure codebase, reduced support overhead, and provided greater deployment flexibility for AWS EKS environments managed through Infrastructure as Code.
