Worked on the qorix-group/score repository to deliver a unified documentation mega-build, focusing on scalable multi-repository support and improved validation quality. Leveraged Sphinx and Python to refactor documentation structure, aligning with the docs-as-code 2.0.0 approach and automating the build process. Addressed validation issues by correcting need IDs and removing repository-specific prefixes, which streamlined error detection and reduced maintenance overhead. The new workflow consolidated documentation validation across repositories, laying the groundwork for easier onboarding of future projects. This work demonstrated a methodical approach to documentation engineering, emphasizing build automation, configuration management, and maintainability within a continuous integration environment.
