Azure Terraform Networking 7+ yrs exp

I need a clean, production-ready Azure foundation written in Terraform and orchestrated through Azure DevOps. The immediate focus is on virtual machines and all networking that supports them—VNets, subnets, NSGs, route tables, Load Balancer, and any peering required between environments.

My objectives are straightforward: reproducible code, clear module structure, and state management that fits an enterprise workflow (remote state in Azure Storage with proper locking). I already have an Azure subscription and a basic DevOps project; what’s missing is the Terraform codebase and any DevOps tasks or variables that let me stand everything up from a single pipeline run.

Please respond with highlights of similar Azure + Terraform builds you’ve delivered and the depth of your experience designing secure, scalable network topologies. If you can point to Git repos or architecture diagrams (sanitized, of course) even better.

Deliverables:
• Terraform modules and root configuration covering VNets, subnets, NSGs, route tables, Load Balancer, and VM definitions
• A working Azure DevOps pipeline yaml (or classic steps) that plans and applies the above to dev, test, and prod stages
• Brief hand-off documentation explaining variables, back-end state config, and how to extend the modules

I’ll test by running the pipeline in my environment; a clean plan/apply with no manual tweaks will be the acceptance criteria.
