Legacy FAQ & RAG-based Chatbots

Context: Enterprise chatbot ecosystem supporting multiple customers with varying data maturity levels.

Challenge: Customers had different data structures – some with structured SQL databases, others with unstructured documents. Needed a unified solution that could handle both.

Solution: Delivered two distinct chatbot types:

• Legacy FAQ bots – SQL‑backed knowledge bases for structured data
• RAG-based intelligent bots – using Qdrant vector search and knowledge graphs (n8n) for intent classification and unstructured data retrieval

Outcome: Successfully deployed across multiple customer environments, enabling each to access AI-powered support regardless of their data infrastructure.
