Customer support teams burn most of their time answering the same handful of questions over and over. This agent takes that load off entirely: it understands what a customer is asking, pulls the accurate answer from your knowledge base using RAG, and holds context across the full conversation — not just a single reply.
The real value is in what it doesn't do. When a query falls outside what it can confidently resolve, it hands off to a human cleanly instead of guessing or looping the customer in circles — so support quality holds up even on the edge cases.
Built on LangGraph and LangChain for the reasoning layer, FastAPI for the backend, giving support teams a first line of response that's fast, accurate, and honest about its own limits.
Built this one for an e-commerce customer behavior project - 18,000+ customers, segmented using RFM (Recency, Frequency, Monetary) analysis.
The interesting part wasn't the segmentation itself, it was what it revealed: nearly 22% of customers were "at risk" of churning, and most businesses wouldn't know that until those customers had already stopped buying.
This is the kind of insight that's usually sitting in your order data already, it just needs the right lens. Happy to take a look at your numbers if you're curious what's hiding in yours.
Tools used: Power BI, SQL, Python (Pandas, Scikit-learn for clustering)
