PROFILE

Jan Stuhlmann

Worked on enhancing the hey-api/openapi-ts repository by improving the reliability of API client query parameter handling. Focused on enabling robust parameter serialization, the work introduced support for a custom paramsSerializer and ensured correct mapping when one is not defined. Utilized TypeScript and JSON to implement and validate these changes, adding comprehensive tests and updating snapshots to confirm correct integration with axios. Addressed a regression by rolling back the package version to restore stability, preventing downstream issues for client integrations. The approach emphasized careful dependency management, thorough testing, and clear documentation updates to maintain a stable and predictable development workflow.
