Andrew also strengthened test coverage with pytest and maintained comprehensive documentation. The depth of his contributions ensured higher data quality, streamlined reporting, and improved maintainability across evolving biomedical data workflows.
February 2026: Delivered data quality and reporting improvements in smaht-portal across TissueSample validation, donor data modeling, and external output workflows. Implemented Tissue Aliquot category validation with regex checks and a new validation function; updated changelog and version bump. Enhanced donor data model with a donor schema in the donors calcprop decorator and added tests for donor calculations on external output files. Refined external output file sample summaries, including tissue categories/types and improved data retrieval methods. Strengthened Tissue Validator by validating external IDs against preservation types and broadening test coverage across multiple preservation types, with multiple bug fixes and a changelog/version bump. Overall, these changes reduce data errors, improve reporting accuracy, and strengthen the data-validation foundation for future features.
