Worked on the rust-lang/this-week-in-rust repository, delivering features focused on benchmarking and optimizing decimal arithmetic in Rust. Designed and implemented reproducible benchmarks comparing floating-point and fixed-point approaches across multiple decimal crates, enabling data-driven decisions for crate selection and performance tuning. Introduced the Lean Decimal Tool, which replaced rust_decimal and achieved 2x to 6x faster performance, improving data processing for weekly content generation. Enhanced documentation by adding a Decimal Crates Comparison and Benchmark section, supporting both English and Chinese readers. Demonstrated skills in Rust, benchmarking, performance analysis, and technical writing, with a focus on clear documentation and measurable performance improvements.

Feb 1, 2026February 2026: Delivered a focused benchmarking initiative to inform decimal arithmetic decisions in rust-lang/this-week-in-rust. Implemented a reproducible benchmark comparing floating-point vs fixed-point implementations across two decimal crates to guide usage decisions and optimization priorities. The change is captured in commit 914e31644393afe6aa3dd936ab299b0244e331cb with the message: Add: Benchmark 2 decimal crates of floating-point vs fixed-point. Impact: provides data-driven insights for crate selection and performance tuning in decimal-heavy code paths. No major bugs fixed this month. Technologies demonstrated include Rust benchmarking, performance analysis, and reproducible experiment design for clear results documentation.
