Worked across deep learning infrastructure projects such as FlagOpen/FlagGems, fla-org/flash-linear-attention, and deepseek-ai/DeepEP, delivering features and fixes that improved model training, inference, and system robustness. Developed optimized CUDA and Triton kernels for attention mechanisms, normalization, and fused activations, integrating comprehensive unit tests and benchmarking to ensure correctness and performance. Enhanced numerical computation reliability with saturating conversions and datatype robustness, and introduced autotuning for scalable attention in Python-based modules. Addressed backend reliability by fixing dispatch logic in token processing. Demonstrated expertise in C++, Python, GPU programming, and performance optimization, consistently focusing on maintainability, cross-platform support, and test-driven development.
In May 2026, the DeepEP project delivered a critical bug fix that strengthens token dispatch robustness in the internode path. By adding the missing num_worst_tokens argument and tightening dispatch logic within the Buffer class, the system now handles worst-case token processing scenarios reliably, reducing risk of dispatch-time failures and improving overall stability for large-scale workloads.

January 2025 monthly summary for intel/sycl-tla: Delivered a key features feature and no major bugs fixed this month. The primary delivery is a saturating conversion from FP16 to signed 8-bit integers (half->int8) with correct handling on CUDA and host paths, ensuring values outside the valid int8 range are clamped to safe limits. This strengthens data integrity in mixed-precision GPU/CPU pipelines and improves numerical robustness for downstream computations. Impact: More reliable numeric conversions across GPU and CPU paths, reducing risk of data corruption and enabling safer, high-performance data processing in the SYCL-TLA stack. Technologies/skills demonstrated: CUDA-host path coordination, saturating arithmetic, cross-architecture data handling, code change management, and alignment with issue #1983.
