Oct 1, 20252025-10 monthly summary for CraftsmenLtd/BloodConnect: Key feature delivered is AWS Resource Tagging Standardization for Terraform-managed AWS resources. A standardized tagging strategy was introduced, including default environment and app/application tags, to improve resource organization, cost allocation, governance, and operational clarity. Implementation progressed through three commits: 2b78f34917db4112d85c2fc12fb24f87609a6e0b, f60ac3643d0d01c9a8cc3b8e4736ac2ce088636e, and 35936f3454d97667b4ac26deb0ecc0fafcf06976, all focusing on adding tags to all resources and the default provider. Major bugs fixed: none reported this month; the focus was feature delivery. Overall impact and accomplishments: this tagging standardization enables better cost reporting, resource organization, governance, and operational clarity, and sets the stage for downstream automation. Technologies/skills demonstrated: Terraform, AWS resource tagging, Infrastructure as Code, no-ticket commits, incremental tagging changes.
