Worked on the sony/model_optimization repository, delivering three features over three months focused on quantization workflow, logging infrastructure, and user guidance. Developed the MCTWrapper to simplify quantization for TensorFlow and PyTorch, enabling easier configuration and export of quantized models. Enhanced backend reliability by implementing a dynamic logging framework in Python, improving observability and maintainability. Authored a Jupyter Notebook tutorial and expanded documentation to guide users through quantization troubleshooting and model compression techniques, leveraging the XQuant Extension Tool. The work emphasized robust API design, cross-backend consistency, and clear documentation, supporting faster experimentation and deployment of optimized machine learning models.
