I will build a rag chatbot using langchain and fastapi


About this gig
Got documents or a knowledge base people keep re-asking the same questions about? I build chatbots that read your content and answer from it not a wrapper that guesses.
I'm Kamran, an AI developer working in LangChain, FastAPI, and vector databases. I built BidForge AI, a RAG proposal engine (LangChain, FastAPI, GROQ, FAISS), presented at CUST Hackathon 2026 plus an OCR document parser for medical PDFs and a few FastAPI/MySQL apps.
What you get:
- Your documents (PDF, docs, site content, or a database) turned into a working chatbot
- Full retrieval pipeline: chunking, embeddings, FAISS vector store
- GPT, Claude, or GROQ whichever fits your budget and speed needs
- A usable interface: Streamlit for internal tools, React if it's client-facing
- Real deployment, not a notebook demo
I won't sell you a full SaaS platform with auth and five dashboards in a $50 gig. I'll tell you honestly what your project actually needs.

FAQ
Do I need to know anything technical to order?
No. Just send me your documents or describe your data source. I'll handle the technical side and explain things in plain terms if you're not from a dev background.
What if I don't have my documents ready yet?
That's fine — message me first and we can scope the project before you order. I'll tell you honestly if your data source will work well for RAG or if it needs cleanup first.

Which AI model will you use — GPT, Claude, or something else?
Depends on your budget and speed needs. GROQ is fast and cheap, GPT/Claude cost more but handle nuance better. I'll recommend one based on your use case, or you can request a specific one.
What's not included in Basic?
Basic is a working single-document RAG chatbot. Multi-document handling, a proper UI, database integration, and auth are Standard/Premium features — check the package comparison so there's no surprise mid-project.
