Developed and integrated a PostgreSQL mutual TLS deployment module within the hashicorp/terraform-aws-terraform-enterprise repository, focusing on automating secure, certificate-based database connections. Leveraging Terraform and HCL, the work enabled mutual TLS authentication for PostgreSQL, enhancing data-in-transit security and supporting repeatable, auditable infrastructure provisioning. The module was fully incorporated into the main Terraform configuration, with a complete release and test cycle validating its integration in Terraform Enterprise environments. This effort demonstrated expertise in Infrastructure as Code, AWS, and mTLS, while emphasizing security-focused automation and reusable Terraform modules to streamline secure database deployments across the repository without introducing new bugs.
