Atta Ur Rehman
@tech143
AI engineer and solution architect for RAG and AI agents
Pakistan
English, Urdu, Hindi
About me
AI engineer building private RAG systems, AI agents and AI voice receptionists that work in real use, not just in demos.
By day I build AI systems for a regulated bank on private infrastructure, so data privacy, guardrails and audit logging are my defaults. As a freelancer I've built a fully offline document research assistant for an enterprise client and delivered a code audit and recovery plan for an AI business platform.
Stack: Python, LangGraph, LangChain, Qdrant, FAISS, FastAPI, Docker, Ollama, Vapi, Retell, n8n.
Tell me the problem and I'll tell you honestly if AI is the right fix.

Atta delivered a highly detailed and professionally structured audit of my software platform. His findings were clearly explained, prioritised by severity and supported with specific references to the codebase. He also distinguished carefully between what could be verified through a read-only review...

Absolute pleasure to work with. Worked with me to understand my requirements and what I needed, and then went above and beyond with what I had expected to come from him. Prepared materials, organized all items and explained the importance of each piece.
