In March 2025, Bruno Ariano developed a PCA Analysis Module for the nf-core/modules repository, enabling Principal Component Analysis on PLINK2 genotype data. He designed the module with a focus on reproducibility and test coverage, integrating environment configuration, main processing logic, and metadata handling. Using Nextflow, Nix, and YAML, Bruno ensured the module outputs eigenvectors, eigenvalues, and comprehensive processing logs to support downstream genomic analyses. His work included implementing end-to-end tests to validate results, emphasizing reliability and maintainability. Over the month, Bruno concentrated on feature delivery rather than bug fixes, demonstrating depth in bioinformatics pipeline development and genomics workflows.
