My Introduction
Aliraza at Google.

I am an AI/ML Engineer with 3+ years of hands-on experience building production-grade intelligent systems. Holding an M.Sc. in AI & ML from Gujarat University, I specialise in Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), agentic pipelines, and enterprise procurement automation. At SITA, I architect AI modules that allow business users to query ERP data through natural language. At Inferenz, I built document intelligence, deep search, and automated drafting platforms. I am driven to push the boundaries of Generative AI and deliver measurable business impact.
