Worked on enabling WebAssembly deployment for PyTorch in the pytorch/pytorch repository by introducing a reproducible Emscripten-based build pathway and resolving operator overload ambiguities between c10::SymInt and size_t for Wasm32 targets. This involved C++ development, build system configuration, and documentation to support reliable WASM builds and broaden deployment options for browser and edge environments. Additionally, contributed to alibaba/MNN by fixing a numeric precision issue in image preprocessing, explicitly defining floating-point literals in C++ to ensure stable training data pipelines. The work emphasized maintainability, traceability, and cross-platform compatibility, leveraging expertise in C++, build systems, and image processing.
