Worked on the satlantis-dev/api-client repository to enhance API client stability and streamline data models, focusing on improving reliability for downstream integrations. Addressed a key bug by refactoring test coverage and simplifying API contracts, which reduced integration risks and made onboarding smoother for client teams. The technical approach involved renaming entities for clarity, such as changing 'placeNote' to 'FeedNote', and removing deprecated functions like 'getPlaceGallery' to maintain a clean codebase. Utilized TypeScript for both development and testing, applying skills in API development, refactoring, and test-driven workflows to deliver a more maintainable and robust client library.
