Worked on stabilizing parameter handling in the Inliner component of the google/error-prone repository, focusing on preventing incorrect inlining into fully-qualified type packages during code replacements. Addressed a subtle transformation issue by implementing a targeted bug fix in Java, ensuring that parameter values are not inappropriately substituted across package boundaries. Developed and integrated a regression test within InlinerTest.java to validate the fix and provide ongoing protection against similar issues. Emphasized thorough testing and code reliability, with all changes verified through continuous integration. Demonstrated strengths in Java development, bug fixing, and automated testing while improving the robustness of code transformation logic.
