Worked on a comprehensive documentation overhaul for the Jij-Inc/ommx repository, focusing on improving clarity, consistency, and user guidance across notebooks, tutorials, and SDK references. Leveraged technical writing skills and Python SDK expertise to restructure and enhance multiple documentation pages, including guides for OMMX adapters and ecosystem components. Utilized Markdown and Jupyter Notebook formats to deliver clear examples and tutorials, such as MIPLIB downloads and OpenJij adapter usage. The effort aimed to streamline onboarding, reduce support needs, and improve maintainability by establishing a consistent structure and traceable references throughout the English documentation, without introducing new features or bug fixes.
