Summary
🤩
Rockstar🎓
Top SchoolLarry Osterman is a Principal Software Design Engineer at Microsoft with deep expertise in systems, APIs, and cloud SDKs, currently shaping language support for the Azure SDK and C++ tooling. With a multi-decade Microsoft career spanning Windows, Exchange, and Confidential Computing, he combines low-level systems design (from network filesystems and audio subsystems to SGX quote validation) with cloud-native service engineering. He led API design and authoring tooling for the Windows Runtime and has driven attestation SDKs across Java, Python, .NET and JavaScript, including machine-generated SDK work and CI/CD/versioning improvements for the widely used Azure SDK repositories. Based in Fall City, Washington, he blends practical engineering—implementing core security and attestation logic integrated with OpenEnclave—with a knack for improving developer experience and test infrastructure. His background in applied mathematics from Carnegie Mellon underpins a methodical approach to complex problems and cross-language interoperability.
