Sean Thomas engineered security and deployment automation for the HHS/simpler-grants-gov repository, focusing on cloud infrastructure and operational reliability. He implemented Terraform-driven AWS Security Hub integration, automated GuardDuty and Inspector monitoring, and enhanced alerting with Lambda and SNS to streamline incident response. His work included hardening S3 access, enforcing EBS encryption, and integrating CloudTrail with CloudWatch for compliance. Sean also stabilized release workflows by orchestrating service deployment order and resolving Docker/ECS file handling issues using Python and Dockerfile. His contributions demonstrated depth in Infrastructure as Code, cloud security, and CI/CD, resulting in improved reliability, compliance, and maintainability across services.

January 2026 — Focused on stabilizing release workflow and file handling for HHS/simpler-grants-gov. Delivered an orchestrated release deployment workflow to enforce service deployment order and enable parallel CI checks, and resolved a critical reliability issue with temporary file handling by restoring proper /tmp permissions and enabling writable /tmp volumes in ECS tasks and release Docker images. These changes improved release reliability, reduced risk of cascading failures, and shortened release cycles. Demonstrated strong deployment automation, Docker/ECS configuration, and CI/CD optimization across services.
