About this gig

Do you need an AI chatbot that answers questions from YOUR data, accurately and without making things up?


I build production-oriented RAG (Retrieval-Augmented Generation) chatbots using Python, LangChain, FastAPI, and modern LLMs.


WHAT YOU GET:

A chatbot trained on your PDFs, docs, or text content

Accurate answers with source citations (reduced hallucinations)

Vector database setup (ChromaDB / FAISS)

Clean REST API (FastAPI) ready to plug into your app

Docker setup for easy deployment

Arabic and English support


WHY WORK WITH ME?

Computer Science graduate specialized in Generative AI

Built multi-agent systems with LangGraph, including Human-in-the-Loop safeguards and automated quality checks

Hands-on experience with RAG, fine-tuning (LoRA), and LLM evaluation (LangSmith)
