“Learn once, write anywhere” has always been React’s promise, but how close are we really to that goal? At React Universe Conf 2025, the Closing Panel brings together leaders from Amazon, Expo, Storybook, Microsoft, and more to discuss what it takes to build React apps across devices and platforms, from mobile and web to desktop, AR/VR, and smart TVs.
Featuring:
- Chris Trag (Head of Evangelism, Amazon)
- Kadi Kraman (Software Developer, Expo)
- Danny Williams (Maintainer, React Native Storybook)
- Mo Gorhom (Senior Software Engineer, Amazon & OSS maintainer)
- Khalef Hosany (Principal Engineering Manager, Microsoft)

Our panelists discuss:
🔹 The reality of “learn once, write anywhere” after 10 years of React Native
🔹 Code sharing percentages: how much is realistic, and where native code still matters
🔹 Platform-specific trade-offs: mobile vs. web vs. desktop vs. TV
🔹 Supporting multiple input modes, screen resolutions, and performance constraints
🔹 Brownfield challenges and bridging native functionality at scale
🔹 Testing strategies: emulators vs. device banks and progressive rollouts
🔹 How AI and automation are changing multi-device React development
The panel closes the conference with candid insights, spicy takes, and practical advice from engineers building React apps for every screen.
