Stephen Shelton engineered deployment and configuration improvements across the 18F/identity-idp and 18F/identity-dashboard repositories, focusing on containerization, CI/CD, and DevOps practices. He standardized login environments and deployment images, aligning YAML and Dockerfile configurations to reduce environment drift and improve reliability. By migrating base images to AWS Public ECR and implementing init containers, Stephen enhanced security and streamlined startup processes. His updates to Nginx configuration enabled better observability and logging in containerized environments. Working primarily with Dockerfile, YAML, and Nginx configuration, Stephen’s contributions addressed cross-repo consistency, deployment stability, and operational efficiency, demonstrating depth in modern infrastructure engineering.
Monthly Summary — August 2025 for 18F/identity-idp: Focused on containerized deployment readiness and observability improvements to accelerate production readiness and reduce deployment risk. Key work updated Nginx config and Dockerfile to support containerized deployments, enabled stdout logging, added temporary directories for Nginx operations, and disabled SSL stapling to avoid issues with self-signed certificates.

December 2024: Migrated identity-idp deployment base images from Docker Hub to AWS Public ECR. Updated Dockerfile to pull base Ruby images from AWS registry, ensuring AWS-backed images are used in both builder and main stages. This reduces external dependencies, improves security posture, and aligns deployment with the AWS-based CI/CD pipeline.

October 2024: Standardized login environments for review apps across identity-idp and identity-dashboard, ensuring consistent PIV URL construction and reducing environment-specific login issues. Normalized LOGIN_ENV in application.yaml to a single value 'reviewapps'. These fixes improve review workflow reliability, speed, and cross-repo maintainability. Demonstrated skills include configuration management, YAML normalization, and cross-team collaboration.
