quality with the team
7 Contribute to feature planning: bring the design perspective to Product Reviews and turn it into a
reasoned decision

EXPERTISE
What you must know about mobile apps:

Native Platforms
You know the difference between iOS and Android:
gestures, navigation patterns, safe areas, system
fonts, screen resolutions, and notch areas
IA & Navigation

and know when to use each. You think in levels of
hierarchy
Performance UX
You know skeleton screens, lazy loading, optimistic
updates, and how to design for slow connections

WCAG contrast, and design with diverse user needs in
mind
Animation & Motion
You can describe transitions and micro-animations for
developers. Familiar with Lottie, easing functions, and

feature
→ Basic understanding of how React Native / Flutter or native development works - so you never design
the impossible
