Worked on the MicrosoftDocs/defender-docs repository to update the Linux Defender for Endpoint release notes, ensuring that documentation accurately reflected a recent hotfix build version. Focused on maintaining release-note integrity, the work involved tracing the update through a single commit and aligning public documentation with internal product releases. Utilized Markdown for precise documentation changes and applied strong version-control practices to support traceability. This update reduced ambiguity for customers and minimized potential support inquiries by providing clear, up-to-date information. The contribution demonstrated attention to detail in documentation and reinforced release governance, leveraging skills in technical writing and documentation management.
