About Me

I'm an AI engineer with a focus on building intelligent systems that leverage Large Language Models (LLMs), RAG (Retrieval-Augmented Generation), and modern vector databases like AstraDB. I enjoy working at the intersection of deep learning, data engineering, and full-stack AI deployment.
