About
Built a demo-live LangGraph/LangSmith LLM agent that translates natural language into SQL against a self-built MLB statistics database, using a vector-store knowledge base of example queries. Focused on predictable orchestration via conditional nodes, YAML-driven behaviors, and tool-gated function calling, with testing via LangSmith and Python scripts.
