Worked on the OpenDCAI/DataFlow repository, delivering enhancements to the Text2SQL pipeline that improved reliability, maintainability, and performance for natural language to SQL translation. Leveraged Python and SQL to refactor core components, standardize parameter naming, and optimize database management, while integrating LLM and embedding services through updated API endpoints. Addressed critical bugs in prompt generation and execution logic, introduced modular pipeline initialization with JSONL datasets, and implemented dependency management strategies for scalable deployments. Focused on robust error handling, caching, and connection pooling, the work enabled faster onboarding, reduced maintenance risk, and established a foundation for extensible, production-ready data workflows.
