Worked on the OfficeDev/office-js-docs-pr repository to prepare and publish a deprecation notice for Office Add-in development in Visual Studio, aligning documentation with the upcoming Visual Studio 2026 roadmap. Focused on technical writing and documentation, the work involved drafting clear guidance in Markdown to inform developers about the deprecation and recommend alternative project creation tools. The update aimed to minimize confusion by outlining migration paths and ensuring that developers have actionable information ahead of the transition. This contribution improved the developer experience by proactively addressing potential disruption and maintaining consistency across official documentation as the platform evolves.
