Hi, I`m Noor ๐
"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, Iโve 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 youโre looking for someone who can turn your data or AI idea into a working solution, Iโd be happy to help.

Most AI projects look great in a demo and break when they meet real work. The agent routes to the wrong tool. The RAG retrieves the wrong chunks. The voice latency kills the conversation. The pipeline runs in a notebook but never makes it to production.
That's where I come in.
In 2 months at a Dubai tech company, I built and deployed 6 production AI services from zero infrastructure. Voice assistants, document tools, RAG pipelines, agent workflows โ all live, all on AWS, all monitored with LangSmith.
