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


About this gig
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,
