Developed and delivered a suite of Polymarket API routes for the RSSHub repository, enabling users to access event details, user trading activity, and leaderboards through integrated Gamma and Data API endpoints. Focused on maintainable API design and route management, the work expanded RSSHub’s route surface with seven new endpoints, all aligned with existing API conventions. Emphasized business value and data accessibility by consolidating route logic and documenting API interactions, while preparing the codebase for production with clean route definitions and basic tests. Utilized TypeScript for implementation, applying skills in API development and route management to ensure a robust integration.
