Worked on enhancing developer-facing features across the lichess-org/api and lichess-org/lila repositories, focusing on both documentation and frontend reliability. Improved the API documentation by clarifying authentication requirements and access levels for study chapters, using Scala and YAML to ensure precise and accessible information for developers. On the frontend, addressed a UI issue in the UblogPost component to conditionally render the 'discuss' link only when appropriate, specifically excluding kid-mode users to prevent broken or irrelevant links. This work demonstrated careful attention to user experience, compliance with kid-mode constraints, and effective cross-repository collaboration within a short project period.
