Hi, my name is Ahjeong Yeom.

About Me

I'm a data and AI professional who helps teams turn complex problems into clear, actionable decisions. Across industries, I’ve seen how the right mix of data, AI, and human judgment can unlock smarter strategies and better products. I’ve led projects that bring structure to messy data, apply practical AI, and deliver tools that make data more useful day to day. With a background in both tech and business, I translate between teams—helping ideas move from insight to impact. Outside of work, I’m drawn to design, fashion, and exploring new AI tools—creative spaces that keep me curious, inspired, and always learning.
