and growth decisions.

I'm a Data Science student at Kookmin University, double majoring in Digital Marketing and currently based in Irvine, California through the Global PBL Program.

I focus on the intersection of data analysis, marketing analytics, and digital content strategy: turning user behavior, campaign signals, and performance data into clear next steps.
