Worked on stabilizing the Advanced Ingestion Pipeline in the infiniflow/ragflow repository, focusing on resolving a critical bug in the Auto Keywords stage. Addressed a runtime failure caused by an incorrect variable reference, which previously disrupted keyword extraction and downstream analytics. The solution involved careful debugging and template variable resolution, reducing manual triage and preventing ingestion failures. Collaborated through disciplined code reviews and clear commit messages, ensuring deployment-safe changes. Utilized skills in bug fixing, data extraction, and pipeline development, with a focus on JSON for configuration and data handling. The work improved pipeline reliability and supported consistent analytics workflows.
