PROFILE

Stephen Shelton

Over seven months, this developer enhanced deployment reliability and security across the 18F/identity-idp and 18F/identity-dashboard repositories by standardizing containerization workflows, improving CI/CD pipelines, and refining configuration management. They migrated Docker images to AWS Public ECR, unified deployment image references, and introduced init containers using YAML and Dockerfile updates. Their work included normalizing Nginx configurations for containerized environments, enabling secure image retrieval via pullthrough cache, and aligning service naming conventions to reduce configuration drift. By leveraging skills in Kubernetes, DevOps, and security, they delivered features that improved startup consistency, reduced operational friction, and strengthened cross-repo maintainability for identity services.
