Top SchoolFei H is a Member of Technical Staff at xAI with 11 years of experience specializing in GPU kernel development, quantization, and end-to-end performance optimization for large language models. Previously a Principal Software Engineer at Microsoft, Fei led infrastructure and R&D to accelerate transformer inference and deployment in production products. His background includes deep contributions to TensorFlow and large-scale distributed ML systems at IBM, where he developed high-performance pipelines for imaging and NLP and earned a Best Demo Paper award. Earlier work at NASA focused on scaling multidimensional scientific data processing in Spark, reducing storage and speeding queries through custom indexes and RDDs. Fei holds a PhD from George Mason University and blends research rigor with production engineering, often bridging low-level CUDA/PTX work and high-level model optimization. Colleagues can expect a pragmatic optimizer who pairs algorithmic insight with measurable system speedups across cloud and edge inference stacks.
