Atiq Ur Rehman

I’m a results-driven AI/ML and Backend Engineer specializing in Generative AI, machine learning, and distributed backend architectures. I build end-to-end AI solutions by integrating large language models with reliable APIs, microservices, and production-ready pipelines.

At Samaritan Technologies, I develop and maintain AI/ML-driven backend services using Python and FastAPI, working with LLMs and Retrieval-Augmented Generation pipelines. I handle data preprocessing with NumPy and Pandas, integrate ML components into production, and design REST APIs with clean, well-tested, version-controlled code.

Previously at Horizon Tech Services (NUST), I engineered real-time voice-based RAG with LiveKit, Deepgram, and ElevenLabs, plus document-grounded question answering. I also built a CrewAI-based guide generator, a LangGraph + Groq ticket resolution system with strict classification and fallback handling, and additional modular backend work including FastMCP services and production systems like event and manufacturing management platforms.
