Off the top of my head, some accomplishments from along the way: - Getting `clap` v3 out (stuck in limbo for years) and then v4 - Polish on and continued maintenance of `typos` - Creation of `trycmd` to test clap's documentation - Making `winnow` - Making `toml_edit` production ready - Getting `cargo add` into Cargo - Mentored the work on Cargo's workspace inheritance - 2 rewrites of `toml` - Creation of `anstyle` and `anstream`, providing an alternative approach to enriching CLIs - Significant work to `cargo release` - Keeping the lights on for many crates at https://github.com/rust-cli/ - Cargo script, from experiments to it being approved for stabilization (stabilization is pending) - Designed and implemented `[lints]` support in Cargo, an idea people had given up on (which I didn't know at the time) - MSRV-aware dependency resolver for Cargo (originally thought impossible with the current code base) - Created a vision and roadmap for improving the test experience for Cargo users - Pulling `snapbox` out of `trycmd` and making it scale to Cargo's needs - Mentored work on Cargo workspace publishing - Led exploration in defining plumbing commands for Cargo - Led exploration in alternative architectures for `cargo fix` to better scale with large workspaces - Advocated for a cross-project, user-centric perspective on build performance - Performance optimizations in Cargo - Spoke at RustNL, GOSIM, Rust in Paris, and RustWeek
