I will build a rag chatbot on your pdfs with fastapi
Rajkumar K
About this gig
I build a private RAG chatbot on your PDFs so your team can ask questions and get answers from your own documents not from the open internet.
You send the files. I index them, wire a FastAPI backend, and give you a simple chat UI. Answers stay grounded in your PDFs. Higher packages add citations, an API you can call from your app, AWS deploy, and basic auth.
What you get
Python FastAPI RAG service (LangChain-style retrieval + LLM)
Chat UI to ask questions on your documents
Answers from your files, with citations on Standard and Premium
Source code on Standard and Premium
AWS deploy + basic auth on Premium
Packages
Basic ($80, 5 days, 1 revision): up to 10 PDFs + chat UI
Standard ($150, 7 days, 2 revisions): citations + FastAPI API
Premium ($300, 14 days, 3 revisions): AWS deploy, auth, source code, production setup
What I need from you
PDFs, any rules (topics the bot should refuse), your LLM API key or I use a placeholder, and where you want it hosted.
Process
Share files and rules. I build and share a test chat. You try real questions. I fix retrieval and prompts. Then I deliver the UI, API, and (on Premium) a working AWS setup you can log into.

I build private Q&A bots on your PDFs and FastAPI backends. You send documents. You get answers with citations, plus an API if you need it.
I have 6 years of software work in Hyderabad: LangChain, LangGraph, FastAPI, AWS Bedrock, Qdrant, and PostgreSQL. I do this at my day job and take small freelance jobs on the side.
Basic work: a chat UI on up to 10 PDFs. Standard: citations plus a FastAPI API. Premium: AWS deploy with basic auth. Send sample PDFs before we start so I can confirm they will work.
FAQ
Do answers stay only on my PDFs?
Yes. The bot retrieves from your uploaded PDFs. It is not meant to browse the open web. If a question is outside your files, it should say it does not know.
