AI & Data Projects

Working at the intersection of design and user needs, I often found myself asking how design could drive greater business impact. That question led me to pursue a two-year diploma in Business and AI Management at the British Columbia Institute of Technology (BCIT), where I deepened my skills in data-driven decision-making, cross-functional collaboration, and AI strategy, bridging the gap between intuitive design and strategic value.
