PROFILE

Stephen Shelton

Stephen Shelton enhanced deployment reliability and maintainability across the 18F/identity-idp and 18F/identity-dashboard repositories by standardizing environment configurations, container images, and deployment workflows. He migrated Docker base images to AWS Public ECR, updated Nginx configurations for containerized logging, and implemented init containers to streamline startup processes. Using skills in CI/CD, Kubernetes, and configuration management, Stephen normalized YAML and Dockerfile configurations to reduce environment drift and support consistent review app behavior. His work improved cross-repo alignment, reduced manual intervention, and increased observability, resulting in faster, more reliable deployments and simplified troubleshooting for identity services in containerized environments.
