Rockstar🎓
Top SchoolJonathan Henson is a Principal Software Engineer specializing in applied AI and systems-level engineering, with 11 years building core infrastructure and SDKs at AWS. He’s contributed significant low-level work across flagship open-source projects—most notably the AWS SDKs (Java v2, C++, and the common C runtime), s2n-tls, and the AWS IoT Python SDK—where his changes touch performance-critical HTTP/CRT integration, CI/CD, and TLS/X.509 security checks. Based in Seattle, he blends compiler and runtime experience from Annapurna Labs with production SDK and tooling expertise at AWS, enabling developer-facing platforms that scale. Colleagues rely on him for cross-platform primitives, lock-free data structures, and pragmatic build/test automation. He’s equally comfortable diving into protocol security and the minutiae of byte-buffer handling, a combination that makes him a go-to engineer for hard systems problems that impact broad developer ecosystems.
