Worked on the OfficeDev/teams-toolkit repository to ensure build stability and maintain release integrity during November 2024. Addressed a critical issue by rolling back a Release Candidate to the previous stable build, prioritizing risk mitigation and reliability for end users. This process involved careful build management and the use of Shell scripting to revert changes and restore a validated state, preserving the planned release timeline. No new features were introduced during this period, as the focus remained on resolving the identified bug and safeguarding the release process. The work demonstrated attention to build workflows and release risk management using Shell.
