NAVER Webtoon • 2020 - 2026
When users got stuck in a loop of 'Recently Viewed' content, new content discovery started to drop.

As Lead Designer, I redesigned the navigation and recommendation structure. By creating a clearer, intent-driven browsing flow, I made it effortless for users to discover new content without disrupting their reading habits.

The Problem: New content discovery was falling because users relied mostly on 'Recently Viewed'. I identified that our discovery flow and information layout needed a complete redesign.

The Solution: As Lead Designer, I drove the end-to-end strategy and rebuilt the information structure. I created a simple browsing flow that helped users find new content faster without disrupting their reading habits.
