PROFILE
Alena Wang
Alena Wang enhanced reliability and observability in large-scale machine learning systems by delivering targeted improvements across two major repositories. In LinkedIn’s Liger-Kernel, she stabilized swiglu patching for Llama4 MoE layers by implementing precise patch-targeting logic in Python, reducing runtime risks and supporting safer experimentation with transformer models. Later, in kubeflow/pipelines, Alena improved backend logging for KFPv2 by ensuring executor logs for failed components are published as accessible artifacts, updating artifact handling, and expanding test coverage. Her work demonstrated depth in backend development, model optimization, and testing, addressing nuanced challenges in both deep learning infrastructure and workflow debugging.

Oct 1, 2025October 2025 focused on stabilizing swiglu patching for Llama4 MoE layers in LinkedIn's Liger-Kernel. Implemented a precise patch-targeting approach that patches shared_expert within MoE layers and patches non-MoE layers directly, and updated the default swiglu parameter to True. This change reduces patching misconfigurations, lowers runtime risk in MoE configurations, and supports safer deployment and experimentation with Llama4 architectures. Commit reference documented for traceability: fix(llama4): Get correct swiglu patch target for llama4 moe layer (#907).
