Willie Xu is a software engineer with 10 years of experience focused on backend systems, cloud tooling, and developer tooling, currently active in the Seattle area. He has contributed substantive features and robustness improvements to high-profile Azure open-source projects—including Azure CLI extensions, Azure SDK for Node, and the core Azure CLI—working on storage preview features, serialization edge cases, and interactive CLI modules. Willie excels at turning complex protocol and data-model edge cases into tested, maintainable code (e.g., polymorphic serialization fixes and account-auth integration for storage). Originally from New York, he blends practical cloud engineering with an interest in machine learning, bringing a user-facing mindset to infrastructure work that improves developer experience.
