Worked on the nf-core/sarek repository to streamline the variant calling pipeline by removing the unsupported Strelka tumor-only somatic variant calling method. Focused on codebase maintenance, this effort involved updating Groovy and Shell scripts, cleaning up related XML configurations, and ensuring all documentation and test cases accurately reflected the changes. The removal reduced the maintenance burden and improved pipeline reliability by eliminating unsupported features, thereby minimizing potential user confusion. Demonstrated skills in bioinformatics, Nextflow pipeline development, and variant calling, while ensuring continuous integration tests passed with the updated configuration. The work contributed to a more maintainable and reproducible workflow.
