PROFILE

Jan Stuhlmann

Jan focused on enhancing the reliability of the hey-api/openapi-ts API client by improving query parameter handling and parameter serialization. Using TypeScript and JSON, Jan implemented support for a custom paramsSerializer, ensuring correct mapping when one is not defined and enabling flexible parameter processing. The work included adding comprehensive tests and updating snapshots to validate serialization behavior, which strengthened the integration with axios and improved overall stability. After identifying a regression, Jan rolled back the package version to restore stability and prevent downstream issues. This work demonstrated a thorough approach to API development, integration, and client-side reliability within a short timeframe.
