Contributed to backend and deep learning infrastructure by enhancing two major open-source repositories. In alibaba/MNN, stabilized the NNAPI backend by implementing robust handling of NC4HW4 constant input tensors, converting them to NCHW or NHWC formats before operand creation to ensure correctness and cross-device compatibility for multi-dimensional inputs. Later, in huggingface/diffusers, delivered a regional compilation optimization for the LongCatImageTransformer2DModel by introducing a _repeated_blocks attribute, which improved image processing performance and resource utilization. Work demonstrated proficiency in C++, Python, and PyTorch, with a focus on backend development, tensor manipulation, and performance-oriented design for machine learning workflows.

Jan 1, 2026Month: 2026-01 – Summary: Delivered regional compilation optimization for LongCatImageTransformer2DModel in huggingface/diffusers by introducing a _repeated_blocks attribute to enable regional compilation, thereby improving image processing performance and efficiency. Implemented via commit 699297f64777796194d6cc84c224082e7faa0c71 (feat: accelerate longcat-image with regional compile (#13019)). No major bugs reported in this repository scope during the month. Impact: higher throughput and lower latency in image generation tasks, improved resource utilization, and a solid foundation for future regional-compile optimizations across models. Technologies/skills demonstrated: Python, PyTorch, Hugging Face diffusers architecture, performance-oriented design, code instrumentation, and PR-driven development.
