PROFILE

Xsank

Over a three-month period, contributed to deep learning infrastructure by integrating ModernBert sequence classification into the jeejeelee/vllm repository, designing new architecture, embedding layers, and attention mechanisms using PyTorch and Python. Enhanced benchmarking flexibility by adding model prefix support and MoE configuration, enabling more robust and configurable model evaluation workflows. Later, optimized the FastVideo kernel in hao-ai-lab/FastVideo by implementing fused Triton GPU kernels for compress and topk operations, replacing a multi-kernel PyTorch pipeline to reduce latency and increase throughput. The work demonstrated expertise in deep learning, GPU programming, and performance optimization, focusing on scalable, maintainable model and kernel engineering.
