Hi 🌿, I'm Gyuyeon (Stella) Jung,
a Product Manager and
UX Researcher.

For 6 years at SK Telecom (Korea's #1 telecom operator with 45% market share and 24M+ users), I've discovered hidden opportunities through UX research and launched features and services while balancing business growth with technical and legal constraints.

Currently, I'm a Master of Information Management and Systems (MIMS) student at UC Berkeley.
