Focused on stabilizing AWS EC2 resource tagging, this developer corrected a misconfigured tag value in ec2.tf, improving environment visibility and supporting accurate cost tracking and governance. Leveraged HCL and Terraform to ensure consistent tagging across environments, reducing the risk of mis-tagged resources and supporting smoother automation. Demonstrated disciplined change management by linking updates to specific commits and issues, maintaining clear documentation and traceability. Additionally, updated environment metadata to reinforce governance, ensuring all changes were auditable and introduced with minimal risk to stability.
