Worked on the appvia/appvia-cicd-workflows repository to enhance the security and governance of Terraform CI/CD pipelines. Introduced SHA256 checksum validation and PR-based artifact naming to ensure the integrity of Terraform plan artifacts, along with a tamper-test harness for added reliability. Improved the Terraform apply workflow by adding manual dispatch controls, refining trigger conditions, and providing clearer feedback on planned changes. Addressed pipeline hygiene by cleaning up YAML formatting to stabilize parsing. Leveraged skills in GitHub Actions, Shell Scripting, and Terraform, focusing on risk reduction, artifact transparency, and maintainability while expanding test coverage for regression safety and pipeline resiliency.
