Worked on the dotnet/SqlClient repository to stabilize the continuous integration pipeline after custom SNI changes disrupted the MDS Main CI and Package pipelines. Addressed the issue by reverting the problematic merge, which restored pipeline reliability and allowed for a thorough root-cause analysis of the failures. Utilized Azure DevOps, PowerShell scripting, and YAML to manage and document the CI/CD workflows, ensuring that future changes could be safely reintroduced with improved validation and rollback strategies. The work focused on maintaining release readiness, isolating risky changes, and planning targeted testing to support robust pipeline management and safer reimplementation of SNI support.
