Portfolio · 2026

AI Engineer & Information Technology Undergraduate

I'm an Information Technology undergraduate passionate about Artificial Intelligence, Machine Learning, and AI Engineering. I build intelligent systems for real-world problems, with a focus on LLMs, Retrieval-Augmented Generation, multi-agent systems, computer vision, and MLOps. My goal is to design production-ready AI that is accurate, efficient, and meaningful.
