Worked on NVIDIA/TransformerEngine, delivering five features and two bug fixes over four months to advance quantized deep learning workflows. Developed FP8 output quantization for GEMM and implemented SwiGLU activation support, updating CUDA kernels, Python bindings, and test coverage to improve inference efficiency and model compatibility. Expanded JAX backend activation support for parity with PyTorch, and enhanced distributed training by integrating FSDP2 and FusedAdam. Addressed robustness in quantized tensor operations by fixing MXFP8 tensor copy and splitting logic, while increasing automated test coverage. Leveraged C++, CUDA, and Python to optimize transformer engine performance, stability, and production readiness for large-scale deployment.

Sep 1, 2025September 2025: Delivered two core features for NVIDIA/TransformerEngine that drive performance, efficiency, and GPT OSS readiness. FP8 Output Quantization for GEMM enables faster, memory-efficient GEMM operations with comprehensive tests across quantizers and data types. SwiGLU Activation Support for GPT OSS extends activation options with updated CUDA kernels, templates, Python bindings, and tests, including clipping of gate/pre-activation values with a scaled sigmoid. Together, these work items improve inference throughput, reduce energy consumption, and broaden model compatibility in production deployments.
