Bio

Hafiz N. is a Generative AI Engineer with over 2 years of experience in designing and deploying large language model systems and multimodal AI solutions for practical applications. His core technologies include LangChain, LangGraph, FastAPI, Flask, and Hugging Face, which he uses to build scalable conversational AI agents, automation pipelines, and structured data generation systems. Hafiz employs MLOps practices using Docker and is proficient in Python, PyTorch, and TensorFlow to deliver low-latency, production-ready AI systems. At Chainfore, he developed a Hybrid RAG system combining Neo4j and Azure AI Search to enhance semantic reasoning and factual accuracy. For Supraz, Hafiz engineered a multi-modal RAG chatbot that improved productivity and data accessibility by automating parts lookup processes. Hafiz holds a Bachelor of Science in Computer Science from the University of Gujrat. He is well-suited for roles that involve building and optimizing AI-driven systems, particularly in environments requiring advanced data processing and automation capabilities.
