Tanjianping worked on stabilizing and refactoring quantization workflows for large language models, focusing on the jeejeelee/vllm and kvcache-ai/sglang repositories. He improved cross-hardware deployment by adding an unquantized fallback for FusedMoE layers, ensuring DeepseekV3.2 compatibility across diverse GPU environments. Using Python and PyTorch, he addressed quantization bugs by refining method selection and unquantization logic, which enhanced model reliability and accuracy. Tanjianping also refactored core utilities and centralized interface functions, reducing code duplication and technical debt. His work demonstrated depth in backend development, machine learning, and quantization, laying a maintainable foundation for future feature expansion.
