Contribution
As the product designer, I led the end-to-end UX of an adaptive learning and coding-practice app by:
- Designing reward and task flows focused on reducing cognitive burden and supporting repeated practice.
- Conducting user interviews and analyzing behavioral patterns to optimize feedback timing and difficulty scaling.
- Building a lightweight design system and interaction patterns suitable for rapid iteration across iOS/Android.
