Worked on the Azure/Microsoft-Defender-for-Cloud repository to enhance the reliability of resource discovery by tags, focusing on a critical bug fix rather than new feature development. Addressed issues in PowerShell scripts related to resource listing, specifically correcting tag-based filtering and pagination logic to ensure accurate identification of resources such as Virtual Machine Scale Sets and Azure Arc machines. Utilized PowerShell scripting and API integration skills to validate end-to-end tag filtering across paginated API responses. The solution improved inventory accuracy, reduced misclassification risk, and strengthened governance and security posture by enabling more reliable resource identification within Azure environments.
