The Problem

Customer support teams were overwhelmed by repetitive, tier-1 technical queries. Existing keyword-based chatbots were rigid, leading to frustrated users and a high escalation rate to human agents.

The Solution

Designed and built a Retrieval-Augmented Generation (RAG) pipeline that embeds Zendesk articles, internal Notion docs, and product manuals into a vector database. The agent dynamically retrieves this factual data to generate highly accurate, contextual answers, completely eliminating hallucinated responses.

System Architecture

How the data flows from the user to the core engine and back.

Core Features

What was specifically engineered for this system.

Semantic similarity search across 10,000+ documents

Real-time streaming responses via WebSockets

Conversation history & memory management

Admin dashboard for reviewing low-confidence answers

Automated syncing with Zendesk knowledge base

Role-based access control and rate limiting

Technical Decisions

FastAPI Backend Integration

Chose FastAPI due to native async support and seamless integration with Python's AI ecosystem.

Pinecone Vector Storage

Selected Pinecone for managed infrastructure and sub-millisecond query latency.

Challenges Solved

Response Accuracy

LLMs naturally hallucinate. Solved by tuning the RAG prompt to strictly say 'I don't know' if context wasn't found in the vector DB.

Data Synchronization

Company docs changed daily. Built a nightly cron job that re-embeds updated articles without causing downtime.

Fast User Experience

LLM generation is slow. Implemented Server-Sent Events (SSE) to stream tokens directly to the UI, reducing perceived latency to under 500ms.
