PROFILE

Baoyuan Qi

Worked on enhancing reliability and performance across two repositories, sleepcoo/sglang and vllm-project/llm-compressor, using Python. In sleepcoo/sglang, addressed critical bugs by correcting a variable reference in the embedding API and removing a duplicate constant declaration, which improved prompt handling and runtime stability. For vllm-project/llm-compressor, delivered a feature upgrade by implementing a multi-process DataLoader that dynamically scales worker processes based on available CPU cores, capped at eight, to accelerate data preparation for large datasets. Demonstrated skills in API development, bug fixing, code refactoring, multiprocessing, and performance optimization, with a focus on maintainable, high-quality engineering solutions.
