PROFILE

Marijan-mihaljev

Marijan Mihaljev spent three months enhancing data ingestion and analytics capabilities across the genestack/openapi and genestack/sdk repositories. He expanded API endpoints to support compressed cell expression imports and introduced new data types, improving scalability and flexibility for large biological datasets. Using Python, YAML, and OpenAPI Specification, Marijan refactored import workflows to enable linking of cells to samples and libraries, clarified data hierarchies, and aligned schema naming across API and documentation. His work emphasized robust data modeling, clear documentation, and maintainable code, reducing integration ambiguity and supporting future extensibility for downstream teams and external partners in biological data processing.
