PROFILE
Ignasi Pérez-ràfols
Over four months, Iñaki Prafols developed and maintained core scientific computing features for the igmhub/picca repository, focusing on astrophysics data workflows. He built a robust 2D mean continuum calculation framework, refactored error handling for FITS file parsing, and introduced a blinding parameter to strengthen experiment integrity. His technical approach emphasized maintainability through code linting, documentation improvements, and dependency management, leveraging Python, Numba, and YAML. By modernizing resource loading and test infrastructure, he improved CI reliability and reproducibility. His work addressed both performance and correctness, resolving edge-case bugs and optimizing numerical computations for large-scale data analysis in astrophysical research.

Jul 1, 2025July 2025 monthly summary for igmhub/picca: Delivered a robust 2D mean continuum calculation framework, advanced 2D extension work, and a suite of refactors that improved correctness and maintainability. Implemented performance optimizations via Numba and parallelization, expanded debugging utilities, and strengthened model structure with A-matrix terms and a bad continuum type. Resolved critical 1D/2D handling edge-cases (hdu_cont, boundary handling) and stabilized the get_mean_cont_method through targeted tests. Achieved a stable baseline by addressing memory considerations (toggle between numbaized and non-numbaized paths) and incorporating essential core processing bug fixes.

May 1, 2025May 2025 monthly summary for igmhub/picca: Delivered targeted documentation improvements and linting fixes to improve maintainability and developer productivity. Specifically, enhanced get_metadata_dict documentation and docstrings in desi_data.py to clarify parameters, returns, and usage, resulting in better readability and lint compliance. No customer-facing features released this month; however, changes reduce onboarding time, minimize lint-related CI blocks, and prepare the codebase for upcoming feature work.
