Developed and integrated the Recount3 RNA-seq Data Retrieval Tool within the galaxyproject/tools-iuc repository, enabling streamlined access to harmonized TCGA and GTEx gene expression data for bioinformatics workflows. Focused on enhancing tool configuration and usability, the work involved refining XML parameters, improving output labels, and updating descriptions for clarity. Leveraged skills in Galaxy tool development, R, and YAML to strengthen validation processes, update test suites, and ensure robust data handling. Emphasized maintainability by refactoring documentation and collaborating on edits, resulting in a tool that improves data accessibility, reliability, and reproducibility for downstream analyses in the Galaxy ecosystem.
