I will build a custom rag chatbot

Are you looking to build a powerful AI chatbot that can answer questions from your own documents, PDFs, or knowledge base? I will build you a custom RAG (Retrieval-Augmented Generation) chatbot using LangChain and OpenAI that actually understands your data.

What I bring to the table:

I am a GenAI Engineer with 3+ years of production experience building LLM-powered systems. I have built RAG platforms handling 50,000+ documents at 91% recall in real production environments not just tutorial projects.

What you will get:

Custom RAG pipeline built on LangChain + OpenAI

Vector database integration (FAISS or ChromaDB)

FastAPI backend with clean API endpoints

Supports PDFs, Word docs, text files

Deployed and ready to use

Full documentation

Tech Stack:

Python · LangChain · OpenAI · FAISS · ChromaDB · FastAPI · AWS/GCP

Why choose me:

I build production-grade AI not just demos. Every system I deliver is clean, documented, and debuggable. I have shipped RAG systems used daily by 20+ engineers in a Fortune 500 healthcare company.

Let's build something that actually works.
