PROFILE

Sudan Bhandari

Over six months, this developer delivered robust data engineering and backend solutions across IFRCGo/go-api, montandon-etl, and pystac-monty repositories. They built and enhanced ETL pipelines for hazard and disaster data, integrating sources like USGS and PDC with asynchronous Celery task orchestration and Pydantic-based validation. Their work included refactoring data models, improving traceability with trace IDs, and migrating token signing to RSA for stronger cryptographic security. Using Python, Django, and SQL, they streamlined data extraction, transformation, and validation workflows, stabilized test suites, and improved GeoJSON asset handling, resulting in scalable, reliable data pipelines and secure, maintainable backend systems.

Sep 1, 2025

September 2025: RSA token signing migration completed in IFRCGo/go-api, introducing RSA private/public key settings and migrating existing tokens to RSA-signed equivalents to ensure only RSA-signed tokens are valid for external usage. The change enhances security posture for external integrations with RSA-based trust chain, with minimal user impact.
