Top SchoolSam Xu is a Principal Software Engineer with 12 years of professional experience and more than eight years of deep C/C++ expertise, currently shaping OData and Graph-related services at Microsoft in Redmond. He combines a strong systems and backend focus—evidenced by substantive contributions to high-profile projects like AspNetCoreOData and ODataSamples—with a history of mobile navigation and map-engine work at Telenav and deCarta. Comfortable across languages and ecosystems (Java, Objective-C, STL, Protobuf, Boost, Qt, OpenGL) he also brings CAD/CAM and routing algorithm experience from an engineering background. Sam pairs hands-on implementation skills with team leadership and a track record of shipping reliability improvements, such as fixing edge-case crashes and refining EDM-to-CLR type mappings in OData. Fluent in English and academically grounded in automotive and CAD/CAM engineering from top Chinese universities, he tends to surface practical fixes that improve interoperability and developer experience rather than just adding features.
