Worked on strengthening the ingestion pipeline and API reliability for the neicnordic/sensitive-data-archive repository, focusing on backend development and error handling using Go. Addressed a dataset parsing issue in SyncAPI and Ingest by implementing robust error handling that logs the root cause while returning a generic, client-friendly message. Corrected a typo in an error message and ensured the process returns after unauthorized responses to prevent cascading failures. These changes improved error observability and made debugging more efficient by clarifying error signals throughout the ingestion pipeline. The work emphasized reliability and maintainability in backend systems, with attention to secure error reporting.
