Worked on the ansible/awx repository to update the Feature Flags API following the removal of the IPv6 feature flag. Focused on validating and maintaining the correctness of API output by updating unit tests to ensure the API returned the expected number of results after the change. Utilized Python and API testing techniques to streamline the feature flag subsystem, reducing its surface area and simplifying ongoing maintenance. The approach emphasized preserving test coverage and output accuracy, contributing to improved stability and lower maintenance costs. Demonstrated attention to detail in unit testing and API validation while addressing a targeted bug fix within the codebase.
