During October 2025, contributed to the microsoft/AzureTRE repository by developing the Plan Core Infrastructure Preview feature. This work introduced a plan-core command within the Makefile, enabling teams to generate a Terraform plan for core infrastructure prior to deployment. The implementation included a new shell script for plan generation and comprehensive updates to the Markdown documentation, ensuring clear guidance for users. By integrating Infrastructure as Code practices and DevOps principles, the feature allows for safer previews, earlier risk detection, and improved governance of infrastructure changes. No bugs were addressed during this period, with efforts focused on delivering this core functionality.
