Boyu Chen developed two targeted features over a two-month period, focusing on backend reliability and platform-aware testing. In CodeLinaro/onnxruntime, he built a dynamic test orchestration mechanism that conditionally skips QNN unit tests based on platform capabilities, using C++ and platform-specific programming to improve test compatibility and reduce CI resource usage. In pytorch/executorch, he implemented a reciprocal decomposition pass, replacing reciprocal operations with division for select backends to address compatibility issues, and added comprehensive unit tests in Python to ensure correctness. His work demonstrated depth in backend development, graph optimization, and robust unit testing across heterogeneous hardware environments.
