Worked on the cds-snc/digital-canada-ca-website repository to enhance infrastructure reliability and governance by addressing deployment risks and configuration drift. Focused on correcting S3 module path references across Terraform and Terragrunt, ensuring that log bucket provisioning used the correct modules for both CloudFront and S3. Downgraded the AWS provider to version 4.67.0, updating constraints and hashes to maintain compatibility and stability across environments. Leveraged skills in AWS, DevOps, and HCL to align module sources and provider versions, improving reproducibility and enabling safer rollbacks. The work resulted in more stable infrastructure and reduced risk during deployments and environment changes.
