Oleguer contributed to the cBioPortal project by enhancing both documentation and data visualization features. In cBioPortal/cbioportal, he updated the About-Us.md file to accurately reflect current team members, improving onboarding clarity and aligning documentation with governance standards. Later, in cBioPortal/cbioportal-frontend, he addressed a data integrity issue in the OncoPrint tabular download feature by refining the data mapping and handling of OQL-derived data for CNA, MUTATIONS, and STRUCTURAL_VARIANT. Using JavaScript, TypeScript, and front-end development skills, Oleguer’s work improved the reliability of exported visualizations and reduced future maintenance overhead, demonstrating careful attention to project accuracy and usability.
