Marketing Data Analyst
Data has
always been
my way of
understanding
people.

I'm Young Jun Song — a Data Science student at Kookmin University, double majoring in Digital Marketing. What excites me isn't the numbers themselves, but what they reveal about how people think, feel, and decide.

I bridge data science and marketing strategy, turning behavior into insight.

Currently based in Irvine, California through the Global PBL Program. I'm drawn to the intersection where consumer behavior meets analytics.

My work spans ML-driven conversion modeling, NLP-based social listening, and data-backed marketing strategy — always with the goal of understanding what actually drives human decisions, not just modeling them.

Actively looking for a Fall 2025 Marketing Data Analyst internship in the U.S.
