Worked on the cds-snc/terraform-modules repository to address a critical issue with AWS WAF resource naming by implementing domain name sanitization within the Terraform simple_static_website module. Used HCL and Terraform to replace dots with dashes in domain names, ensuring compatibility with WAFv2 resource and metric naming requirements. This fix eliminated apply-time errors during deployments, improving reliability and reducing the risk of rollbacks. The update also enhanced consistency in S3 bucket and WAF resource naming, aligning with AWS best practices for infrastructure as code. Demonstrated attention to deployment reliability and adherence to cloud infrastructure standards using AWS and Terraform.
