Accompany users to build good habits within 21 days
From May 2024 to February 2025, I worked in the Internet Influencer BU, where our team constantly experimented to explore the potential of the KOL economy. After many rounds of trial and error, the Habit Charger App emerged as the project that truly stood out and left a lasting impact.
Together with Waki, our mission was to create an app from 0 to 1 that offers a seamless, engaging, and cohesive behavior-change experience—helping users cultivate a healthier and happier lifestyle.
As the sole designer, I owned the end-to-end product design process from 0 to 1, covering everything from problem definition to the delivery of final visual artifacts, with occasional support from a senior designer for critical priorities.
Took on hybrid responsibilities beyond design, including product planning, delivery management, meeting facilitation, and marketing copywriting (e.g., landing page).
Bridged cross-functional communication in the absence of a full-time PM, ensuring alignment across product, engineering, and business stakeholders.
Collaborated closely with BU Head, engineers, QAs, marketing specialists, customer service, and other supporting teams to drive product success.
