About this gig

Are you drowning in documents? Need a chatbot that actually knows your data not just generic internet answers?


I build production-grade Retrieval-Augmented Generation (RAG) systems and LLM applications tailored to your use case whether that's a PDF Q&A bot, a database query interface, or a full multi-agent workflow.


What I build:

  • RAG pipelines over PDFs, CSVs, websites, or databases
  • LLM chatbots with conversation memory and source citations
  • NL-to-SQL agents (ask your database in plain English)
  • Multi-agent systems for complex reasoning workflows
  • FastAPI backends + Streamlit/React frontends
  • Dockerized, deployment-ready packages


Tech stack: LangChain · LangGraph · FAISS · ChromaDB · OpenAI / Groq / HuggingFace · FastAPI · Docker · Python


Why me: I'm an AI/ML engineer with hands-on experience deploying RAG chatbots for real clients (see my portfolio: github.com/farheenfathimaa/project-portfolio). I write clean, documented code not just working demos.


You get: well-structured GitHub repo, environment setup instructions, and a README you can actually follow.


Let's discuss your use case before you order I want make sure I deliver exactly what you need.
