Developed contributor-facing documentation for the sxs-collaboration/www_black-holes_org repository by implementing a Markdown-based biography and research profile feature. This work involved creating a structured profile file to document contributor background, research projects, and contact information, supporting improved onboarding and collaboration within the project. Leveraging skills in academic writing, research, and documentation, the developer ensured that the new materials were clear, traceable, and easily maintainable. The approach emphasized transparency and accessibility, integrating the new documentation into standard onboarding resources. The solution was delivered as a single feature, focusing on content quality and process clarity without introducing bug fixes during the period.
