GitHub Sponsors Profile
I work on the Rust standard library API team reviewing every API change to the standard library.
I maintain foundational Rust crates including serde, syn, quote that practically everyone working with Rust will use. As of 2025, 65% of all published crates on crates.io depend transitively on syn; 43% depend transitively on serde; 45% depend directly on at least one crate by me.
I create teaching material for advanced Rust concepts including my case studies project, procedural macro workshop, and Rust quiz.
I set an example for thoughtful Rust library design, as seen in anyhow or thiserror.
I have earned a reputation for regularly coming up with highly creative, odd but ultimately highly valuable ideas.
Some examples of interesting projects:
Watt, a runtime for executing Rust procedural macros compiled as WebAssembly designed to provide faster compilation, isolation, and determinism.
Async-trait, a macro for using async functions in Rust traits with dynamic dispatch.
No-panic, make the compiler verify it's impossible for a function to panic.
Cargo-expand, Cargo subcommand to show the result of macro expansion.
Trybuild, a library for testing the diagnostics a user would see from an incorrect macro call.
Prettyplease, a lightweight pretty-printer that is well suited to generated code and much faster than rustfmt.
