Profile

I build useful systems where product, AI, and infrastructure meet.

I am a final-year undergraduate at Singapore Management University, pursuing a Bachelor of Science in Information Systems with a double major in Product Development and Artificial Intelligence.

My work sits between software engineering, cloud architecture, and user-centered product thinking. Rather than just shipping features, I like understanding why a system should exist, who it serves, and how to make it reliable enough to matter.
