Tunjian worked across several deep learning infrastructure projects, focusing on GPU compatibility and quantization support. On the linkedin/Liger-Kernel repository, he expanded AMD ROCm support by adapting kernel parameters and streamlining CI workflows using Python and YAML, which improved hardware reach and developer onboarding. For HabanaAI/vllm-fork, he enhanced quantization documentation to clarify hardware compatibility, reducing integration risk. In vllm-project/vllm-projecthub.io.git, he authored technical guides and benchmarks for PTPC-FP8 quantization on AMD ROCm, supporting enterprise adoption. On bytedance-iaas/vllm, he maintained stability by reverting complex ROCm integrations in RotaryEmbedding, demonstrating depth in GPU programming and PyTorch.

November 2024: Expanded hardware reach by delivering AMD ROCm support for the Liger Kernel, preparing Liger-Kernel for ROCm-enabled AMD GPUs. Work focused on adapting the num_warps parameter, updating dependencies, and modifying kernel configurations to ensure proper execution on AMD hardware. This lays groundwork for broader cross-vendor GPU compatibility and strengthens our position for ROCm-enabled deployments.
