Terraform & Reusable Modules

Copy-pasted infrastructure code drifts apart environment by environment until no two are the same and none can be trusted. I write Terraform or OpenTofu as well-factored, versioned modules that encode your landing zones and account foundations once and reuse them everywhere, with remote state and locking so concurrent changes can't corrupt each other. Every change is a reviewed plan read before it's applied, with drift detection catching the manual console edits that quietly undermine reproducibility — so infrastructure stays as auditable and safe to change as application code.
