I find it remarkable that one person with just over a year of Rust experience can successfully rewrite ~6000 lines of well-tested, highly tuned Fortran in Rust and end up with similar performance on benchmarks without having in-depth expertise in the domain (simulation of fluid dynamics). The benchmarks (https://mckeogh.tech/post/shallow-water/84896735-54a97580-b0...) show similar performance across all input sizes for both the old Fortran and the new Rust code, with Fortran outperforming in some cases and Rust outperforming in others.
