PROFILE

Javier Herrer

Worked on stabilizing and improving the Airflow-Livy integration within the gopidesupavan/airflow repository, focusing on backend reliability and documentation clarity. Addressed a bug in the LivyAsyncHook by ensuring extra_headers were consistently transmitted in all API calls, which enhanced the security and reliability of custom header propagation when fetching batch state and logs. Introduced targeted unit tests to validate these changes, reinforcing confidence in API integration workflows. Additionally, updated documentation to accurately reflect the correct Livy connection string scheme, reducing potential misconfiguration. Utilized Python and RST, with an emphasis on backend development, API integration, and comprehensive unit testing.
