Worked on the keras-team/keras repository to expand operator coverage in the Keras OpenVINO backend by implementing support for the Numpy.meshgrid operation. Developed a robust meshgrid function in Python, incorporating input validation and precise handling of output shapes for both 'xy' and 'ij' indexing modes. Updated the backend’s test strategy by removing meshgrid from the excluded concrete tests, thereby improving test coverage and deployment reliability. Leveraged backend development skills with Keras, NumPy, and OpenVINO to enhance model portability and performance, addressing maintenance gaps and strengthening cross-framework integration for OpenVINO-backed workflows within the Keras ecosystem.
