I will build an ai chatbot with rag, openai, langchain or langgraph

I build custom RAG chatbots and document-aware AI assistants using OpenAI, LangChain/LangGraph, and FastAPI.

This gig is for practical AI systems that answer questions from your documents, PDFs, website content, FAQs, internal notes, or structured data. Depending on the package, I can deliver a simple prototype, a backend API, Docker-ready code, basic evaluation tests, CI/CD guidance, and clear setup documentation.

Scope can include:

- Document ingestion and chunking

- Vector search / retrieval setup

- OpenAI integration

- RAG prompt design

- FastAPI backend endpoints

- Source-aware responses

- Basic evaluation questions

- Docker setup and documentation

- CI/CD or cloud deployment guidance

This gig does not include large-scale production deployment, long-term maintenance, paid API usage, hosting fees, domain setup, enterprise security, or unlimited data ingestion unless agreed as extras or a custom offer.

Best for founders, startups, consultants, and small teams who want a working AI assistant or backend prototype they can test, extend, and integrate.

Please message me before ordering so we can define the data sources, expected behavior, technical scope,
