Abstract

I am a Computer Science undergraduate at Nanyang Technological University, currently building across full-stack engineering, intelligent interfaces, and applied AI systems.

My recent work spans enterprise software engineering at ST Engineering, research-driven interface design as a Research Assistant at MICL Lab, and coursework across reinforcement learning, artificial intelligence, machine learning, and security.

This page is reconstructed from my existing portfolio and resume data into a compact web CV, preserving the paper-like reading flow while moving the stack to Next.js.
