Worked on the NOAA-FIMS/FIMS repository to enhance the reliability and robustness of both optimization routines and CI infrastructure. Focused on improving the fit_fims pipeline by wrapping nlminb optimizer calls in tryCatch blocks using R, which provided clearer error feedback and prevented silent failures during statistical modeling. Developed helper functions to standardize diagnostics and enforced explicit handling of non-finite objective values. Additionally, addressed CI reliability by replacing fallocate with dd for swap file creation in Bash scripts, ensuring stable resource allocation on Ubuntu runners. These efforts improved error handling, diagnostic clarity, and test stability within a DevOps and CI/CD context.
