Senior🎓
Top SchoolPatrick Xu is a Senior Software Engineer II based in Shanghai with 11 years of experience building scalable backend systems and research-driven features for cloud-native infrastructure. At Zilliz he has moved from research roles into senior engineering, contributing to Milvus—a high-performance vector database—where he enhanced storage, indexing, partition isolation and materialized view capabilities. He blends systems-level C++/Go work with practical testing and serialization improvements, showing both depth in core components and an eye for query optimization. A creative self-learner, Patrick’s background includes implementing diverse LSH methods during research at the University of Melbourne, reflecting a strong footing in similarity search and vector retrieval. He’s comfortable shipping production features and improving test frameworks, and often surfaces non-obvious optimizations that bridge research ideas and deployable engineering.
