About this gig

including a two-company comparison mode and streaming responses. It's containerized with Docker and also covers India (NSE) and Germany (XETRA) filings.


For this gig, I'll build you a similar RAG chatbot tailored to your documents: upload your PDFs/text, and I'll set up the retrieval pipeline, connect it to Claude or OpenAI, and deliver working code with source citations in every answer.


What you get:

  • A working RAG pipeline (chunking, embeddings, vector store)
  • - Claude or OpenAI API integration with citation-grounded answers
  • - Clean, documented Python code (FastAPI backend)
  • - A simple chat interface to test it

  • I'll ask a few questions upfront about your documents and use case so the scope is clear before I start. Message me and let's talk about your project.a Python full-stack developer specializing in retrieval-augmented generation (RAG) and LLM API integrations.


I built FilingIQ, a multi-company RAG assistant that auto-fetches SEC EDGAR filings, chunks and embeds them locally, persists vectors in ChromaDB, and answers questions with citation-grounded responses via the Claude API Hi, I'm Vijay
