Summary
🤩
Rockstar🎓
Top SchoolJames Mayclin is a senior software engineer with nine years of experience focused on backend and security engineering, currently improving the AWS customer security experience as a Sr. SDE in Seattle. He contributes to core open-source projects like aws/s2n-tls and s2n-quic, where his work on refactors, code coverage, and cross-compilation increased maintainability and platform-tested security of TLS implementations. Comfortable in Rust and JavaScript, he brings practical systems experience from AWS and earlier roles building backend services for AI classifiers and high-throughput messaging platforms. A Stanford BS in Mathematical and Computational Science with a background teaching CS and coaching voice, he blends rigorous technical judgment with clear communication and attention to usability. Notably, he’s applied low-level protocol hardening and cross-platform tooling to raise the bar on real-world cryptographic code quality.
