PROFILE
Yihan Wang
Worked extensively on the NVIDIA/TensorRT-LLM repository, delivering features and fixes that improved inference performance, code maintainability, and testing reliability for large language models. Leveraged C++, Python, and CUDA to implement advanced attention mechanisms, optimize KV-cache management, and automate dependency upgrades, ensuring compatibility and efficient memory usage. Enhanced CI/CD pipelines and testing workflows to reduce flakiness and accelerate release cycles, while addressing memory safety and symbol collision issues for robust production deployments. Contributed to backend development by unifying buffer management and streamlining installation processes, resulting in more predictable, maintainable, and high-throughput inference paths across evolving deep learning workloads.
