Developed robust identity and notification infrastructure within the navapbc/template-infra repository, focusing on secure, environment-aware deployment for AWS resources. Leveraged Terraform and HCL to deliver dynamic configuration of Cognito user pools, clients, and SES email identities, introducing domain and hosted zone gating to ensure features activate only under defined conditions. Emphasized disciplined change management by reverting exploratory identity and notification changes for the pfml-starter-kit-app, maintaining stability across environments. Prioritized safeguards to minimize misconfiguration and exposure, demonstrating a methodical approach to infrastructure as code. The work reflects a strong foundation in DevOps practices and cloud-native automation for scalable, secure deployments.
