During June 2025, Leimy focused on stabilizing the WebNN and TFLite integration within the mozilla/gecko-dev repository by addressing a regression in the QDQ fusion path for element-wise logical operations. Using JavaScript and leveraging skills in testing and revert workflows, Leimy reverted a previous optimization that had introduced web-platform-test failures in certain build configurations. This targeted change restored stability and ensured reliable test outcomes while preserving performance improvements in unaffected areas. The work included thorough validation against test suites and CI pipelines, careful documentation of the rationale, and clear communication with QA and downstream consumers to minimize disruption.
