PROFILE
Mingjie Li
Worked on the IGVF-DACC/igvf-catalog repository, delivering a range of backend features and enhancements focused on data indexing, API robustness, and batch processing. Developed and refined APIs for variant, phenotype, and biosample relationships, standardized naming conventions, and improved schema flexibility to support evolving data models. Enhanced OpenAPI documentation for genomic coordinates and implemented error handling and timeouts for more reliable endpoints. Leveraged Python, TypeScript, and ArangoDB to optimize database querying, batch data retrieval, and ontology mapping. Prioritized maintainability through code refactoring, linting, and dependency management, resulting in a more scalable, reliable, and developer-friendly data catalog platform.

Apr 1, 2026IGVF-DACC/igvf-catalog — April 2026 performance summary. Delivered batch data retrieval and batch processing enhancements for IGVF data APIs, enabling multi-ID batch requests and improving reliability and API performance. Overhauled the GWAS data adapter and ontology mappings to strengthen data integrity, searchability, and schema alignment. Implemented API compatibility refinements and targeted refactors (e.g., staticmethod usage) to support scalable batch operations. Fixed key tests and edge cases to stabilize the release. Result: faster batch processing, more robust data ingest, and improved data discoverability across the catalog.
