I build production-grade agentic AI systems — multi-agent pipelines, enterprise RAG platforms, and end-to-end LLM-powered products that actually ship. My recent work includes: A 10-node LangGraph RAG platform (NexusIQ) that unifies Confluence, Slack, Jira, Google Drive, and PDFs with hybrid vector + BM25 retrieval, cross-encoder reranking, and a hallucination guard — all under 2 seconds end-to-end. An autonomous B2B SDR agent, that handles lead discovery, qualification scoring, and personalised email drafting with human-in-the-loop approval via checkpointed LangGraph state machines. A real-time Pakistan Sign Language recognition system (D-VOICE) achieving 98.25% test accuracy using a hybrid TCN+Transformer model on MediaPipe landmarks — full-stack, live inference, deployed. A fully autonomous visual novel video generator that converts a natural-language prompt into a 60 second cinematic video via 4 specialised LangGraph agents — 66/66 tests passing. What I bring to your project: → Deep LangGraph expertise: state machines, interrupts, checkpointers, multi-agent coordination → Production RAG: hybrid dense + sparse retrieval, RRF fusion, reranking, hallucination detection → Full-stack delivery: FastAPI backends, React/Next.js frontends, PostgreSQL/MongoDB, Docker → Automation & no-code: n8n, Make, and Zapier for workflow automation and API integrations — useful when you need fast turnaround without custom code → Cloud: AWS experience (EC2, S3, Lambda) for deployment and infrastructure → Clean, documented code with real test coverage not just demos I'm a CS graduate, I work like a senior engineer: I scope projects carefully, communicate proactively, and deliver systems that hold up in production not just prototypes. If you're building an AI agent, a RAG system, an LLM-powered product, or need to automate workflows with n8n/Make/Zapier — or just need someone to turn a complex idea into working software, let's talk.

Hi, I`m Noor 👋 "I turn raw data into clear, actionable insights that empower better decisions and drive real results, every step of the way." I'm a Data Scientist and AI Engineer. Over the past 5+ years, I’ve worked on projects that combine data engineering, machine learning, and large language models to build intelligent, production-ready solutions. I specialize in designing end-to-end ML pipelines, developing LLM-powered applications (RAG, LangChain, Llama-2/3, OpenAI), and deploying scalable systems on Azure, Databricks, and Docker. My work often involves automating data workflows, improving prediction accuracy, and transforming complex data into clear insights. Some of my favorite projects include building an AI chatbot for e-commerce, a predictive system for event planning, and an IoT protocol translator using LLMs. I value clarity, efficiency, and collaboration and I always aim to deliver results that make a measurable impact. If you’re looking for someone who can turn your data or AI idea into a working solution, I’d be happy to help.
