Developed and delivered a nf-core compliant Cosine Similarity Calculation Module within the nf-core/modules repository, focusing on enhancing code quality and maintainability for bioinformatics pipelines. The work involved refactoring the module structure for improved organization, aligning configurations with nf-core standards, and implementing dynamic versioning using Nextflow and YAML. Extensive quality controls were introduced, including linting fixes, schema alignment, and removal of unused dependencies. Expanded test coverage and comprehensive documentation were added to ensure robustness and clarity. This module enables reliable cosine-based analyses in downstream workflows, leveraging R programming and data analysis skills to support reproducible and maintainable scientific computation.
