About

Built and deployed a production agentic LLM knowledge assistant that answers complex questions over internal documents, APIs, and databases using a RAG architecture (FAISS/Pinecone) and LangChain/LangGraph orchestration. Emphasizes production-grade reliability and hallucination control through grounding, confidence thresholds, validation, retries/fallbacks, and full observability (logging/metrics/traces) with continuous evaluation and feedback loops.

Key Strengths

  • Built and deployed production agentic LLM knowledge assistant across internal docs, APIs, and databases
  • Strong RAG architecture implementation with vector search (FAISS/Pinecone) for grounded answers
