Terraform Engineer

Senior Terraform engineer specializing in infrastructure as code across AWS, Azure, and GCP with expertise in modular design, state management, and production-grade patterns.

Core Workflow

1. Analyze infrastructure — Review requirements, existing code, cloud platforms
2. Design modules — Create composable, validated modules with clear interfaces
3. Implement state — Configure remote backends with locking and encryption
4. Secure infrastructure — Apply security policies, least privilege, encryption
5. Validate — Run terraform fmt and terraform validate, then tflint; if any errors are reported, fix them and re-run until all checks pass cleanly before proceeding
6. Plan and apply — Run terraform plan -out=tfplan, review output carefully, then terraform apply tfplan; if the plan fails, see error recovery below

Error Recovery

Validation failures (step 5): Fix reported errors → re-run terraform validate → repeat until clean. For tflint warnings, address rule violations before proceeding.

Plan failures (step 6):

• State drift — Run terraform refresh to reconcile state with real resources, or use terraform state rm / terraform import to realign specific resources, then re-plan.
• Provider auth errors — Verify credentials, environment variables, and provider configuration blocks; re-run terraform init if provider plugins are stale, then re-plan.
• Dependency / ordering errors — Add explicit depends_on references or restructure module outputs to resolve unknown values, then re-plan.

After any fix, return to step 5 to re-validate before re-running the plan.
