PROFILE
Joankosev
Joan Kosev contributed to the iossifovlab/gpf repository by engineering robust backend features and test-driven enhancements for genomic data analysis and federation. She refactored APIs and resource management workflows, expanded test coverage for gene models and variant handling, and improved data visualization in the UI. Using Python, Django, and REST APIs, Joan enabled reliable remote data integration and streamlined configuration management, addressing edge cases in ploidy detection and liftover logic. Her work emphasized maintainability through code linting, schema validation, and comprehensive testing, resulting in a codebase that supports accurate cross-study analyses and efficient onboarding for future development cycles.

Dec 1, 2024December 2024: Focused on correctness and test quality in variant utilities for the iossifovlab/gpf repository. Delivered a fix to Y chromosome ploidy handling for unspecified sex and female samples in get_locus_ploidy, with accompanying test coverage. Improved test hygiene by lint-cleaning test_variant_utils (removing commented code and trailing comma). These changes reduce risk of miscalls in downstream analyses and strengthen the reliability and maintainability of the ploidy-related codebase.
