Worked on cross-repository CI/CD security hardening for the Microsoft Graph SDKs, focusing on the msgraph-sdk-dotnet, msgraph-sdk-go, msgraph-sdk-java, and msgraph-sdk-typescript repositories. Upgraded the create-github-app-token GitHub Action to version 3, enhancing token generation security and improving build reliability across Go, Java, and TypeScript SDKs. Standardized token management and CI workflows, aligning with Dependabot-managed dependencies to reduce maintenance risk and build-time failures. Leveraged skills in CI/CD, DevOps, and GitHub Actions to deliver consistent security improvements, enabling faster cross-language development and more reliable releases while ensuring maintainability and reducing operational overhead for multi-language SDK pipelines.
