Julia Reynolds engineered robust cloud infrastructure and deployment automation across the CMSgov/ab2d-bcda-dpc-platform and CMSgov/ab2d repositories, focusing on secure configuration management, scalable provisioning, and incident-ready operations. She designed Terraform-based modules for ECS/Fargate migration, centralized S3 logging, and standardized backup policies, while integrating CI/CD pipelines using GitHub Actions and Packer. Julia implemented mTLS-based inter-service communication, SOPS-driven secret management, and IAM policy refinements to strengthen security and compliance. Leveraging languages such as Bash, HCL, and YAML, her work emphasized repeatable, auditable workflows and cross-environment consistency, resulting in resilient deployments and improved developer velocity through automation and clear documentation.

August 2025 performance summary for CMSgov/ab2d-bcda-dpc-platform focused on stabilizing CI/CD and strengthening Lambda security postures. Two key outcomes: (1) CI/CD Trust Policy Alignment on GitHub Actions updates Terraform configurations to remove references to the archived ab2d-lambdas repo and ensures the Actions role uses the correct repository trust policy; manual testing in non-production environments confirmed the workflow succeeds after changes. (2) Lambda KMS Permissions Incident Resolution broadened Lambda IAM policy to allow kms:Encrypt and kms:Decrypt on all resources, enabling Lambdas to encrypt/decrypt across resources and addressing a BCDA incident. Overall impact: Improved deployment reliability, reduced risk of broken CI/CD due to outdated references, and a stronger security posture for cross-resource encryption, leading to faster incident containment and safer production runs. Technologies/skills demonstrated: Terraform configuration management, GitHub Actions CI/CD, IAM policy management, AWS Lambda, AWS KMS, non-prod testing and validation, incident response coordination.
