Rockstar🎓
Top SchoolAdam Foxman is a Principal Software Engineer at Microsoft with decades of low-level systems experience in C, C++ and C#, specializing in high-concurrency, high-performance backend systems and platform tooling. He has driven performance and reliability work across database engines, virtualization, MSN/Office365 services, and the React Native ecosystem, often squeezing every last bit of hardware and OS capability for measurable wins. A hands-on leader and mentor, he has modernized thousands of projects to .NET SDK-style, cut Office365 update runtime by 68% while eliminating significant network costs, and led cross-company efforts that advanced React Native tooling and community adoption. He combines deep technical craft—building non-blocking hash tables and I/O-safe recovery paths—with a people-first approach, consistently fostering high-performing, collaborative teams. Active in open source, he launched a widely noticed React Native toolkit and contributed substantial build-system and CLI work to rnx-kit. Based in Redmond, he pairs metal-to-cloud technical depth with empathy and a knack for turning ambiguous, cross-organizational problems into delivered outcomes.
