Summary
🤩
Rockstar🎓
Top SchoolNoah Kennedy is a Systems Software Engineer with a decade of experience building high-performance networking and runtime systems, currently contributing to Cloudflare’s Pingora project. A core member of the tokio.rs team, he has improved async I/O and reduced syscalls across tokio and tokio-uring, and helped harden userspace WireGuard in Rust via cryptographic benchmarking and FFI work on boringtun. Comfortable across low-level systems, networking, and performance tuning, he pairs deep debugging and tracing expertise with pragmatic refactors that improve maintainability. Based in Austin, he blends production systems work with an almost obsessive interest in network performance and runtime internals, often learning unfamiliar technologies rapidly and shipping production-ready changes within a week.

An io_uring backed runtime for Rust
Role in this project:Back-end Developer
Back-end DeveloperContributions:4 releases, 187 reviews, 24 commits in 11 months
Contributions summary:Noah primarily contributed to the `tokio-uring` project by refactoring and optimizing the io_uring-backed runtime for Rust. Their work involved implementing features, improving the codebase structure and managing operations. Key contributions include batch request submissions, fixing clippy lints, refactoring the post-op logic into completable and restructuring the runtime. These changes improve runtime performance and add additional features.
