Ewa Stempel engineered robust access management and security automation for the ministryofjustice/modernisation-platform and aws-root-account repositories, focusing on governance, auditability, and operational stability. She implemented IAM user lifecycle controls, structured change management, and permission sets using Terraform, YAML, and Shell scripting, enabling precise access control and streamlined compliance. Ewa unified and hardened GitHub Actions workflows for link validation and automated security scanning, reducing technical debt and improving incident readiness. Her work addressed deployment stability, reduced false positives in validation, and simplified QA tooling, demonstrating depth in infrastructure as code, CI/CD, and security management while supporting scalable, maintainable cloud infrastructure for the organization.
