PROFILE
Kristinawlai
Over a nine-month period, contributed to the UCD-SERG/serocalculator repository by developing and refining a robust R package for serological data analysis and visualization. The work focused on API modernization, data ingestion reliability, and release management, including major API renames, deprecation paths, and enhanced documentation. Leveraging R, JavaScript, and YAML, implemented features such as built-in dataset integration, improved plotting frameworks, and automated CI/CD workflows. Addressed code quality through extensive refactoring, linting, and expanded test coverage, while streamlining CRAN and GitHub release processes. These efforts improved usability, maintainability, and reproducibility, supporting both end-user adoption and downstream analytical workflows.

Jan 1, 2025January 2025 performance for UCD-SERG/serocalculator focused on data source consolidation, packaging hygiene, test stability, and release readiness. Key deliverables include migrating from OSF-driven external data to built-in package datasets, moving files to extdata and converting to CSV/RDS, with corresponding load-function updates to remove OSF references. Packaging, documentation, and CRAN-readiness were enhanced through versioning, NEWS updates, and documentation improvements, including CRAN-compliant notes and guidance. The test suite was strengthened by migrating to test datasets, updating tests and snapshots, and re-enabling donttest/dontrun where appropriate. The codebase was cleaned of OSF references and unnecessary data-raw artifacts, and an internal API exposure pathway via ::: was added to support internal usage/tests. The removal of any::metaplus dependency simplified the dependency surface. A successful CRAN submission was tracked and reflected in the release workflow. These efforts improved reproducibility, reliability, and maintainability, and position the package for smoother future releases.
