Szu-yun-ko
Worked on the NOAA-FIMS/FIMS repository, focusing on backend development and model transparency for fisheries stock assessment software. Over three months, delivered three features including enhanced documentation with Doxygen and LaTeX formulas for core C++ functions, improving clarity and validation for auditors and users. Refactored the codebase to integrate the TMBad framework, removing conditional macros and streamlining header management for maintainability. Implemented R-configurable sex parameterization, exposing proportion_female as an R scalar and wiring it through C++ vectors to enable dynamic, sex-specific calculations. Demonstrated strong skills in C++, R, Rcpp, and software engineering, emphasizing maintainable, well-documented, and flexible scientific code.

May 1, 2026May 2026 NOAA-FIMS/FIMS: Implemented R-configurable sex parameterization to enable sex-specific derived quantities. Exposed proportion_female as an R scalar (default 0.5), wired through initialization, and broadcast to per-age C++ vectors at TMB build time, enabling dynamic, researcher-controlled calculations from R.
