React Native developers are all too familiar with the pain of long native build times—especially in CI environments. But what if you could skip most of that?

In this talk from Callstack’s React Universe Meetup in San Francisco, Principal Engineer Michał Pierzchała introduces a brand-new open-source framework from the Callstack team: React Native Enterprise Framework (RNEF. Designed for large-scale teams and production-scale apps, it dramatically reduces build times and improves dev experience by reusing native artifacts across machines and environments.

You’ll get a live demo of how Expensify uses React Native Enterprise Framework to cut iOS builds from 30 minutes to seconds. Michał walks through how the framework works, how to adopt it incrementally (even in brownfield apps), and what’s coming next.

What you’ll learn:

• How remote caching enables CI-native builds in seconds
• How RNEF integrates with GitHub Actions for smart artifact reuse
• What makes RNEF modular, self-hostable, and enterprise-ready
• How to adopt it in existing React Native CLI projects

Whether you're scaling a growing app or just tired of waiting for builds to finish, this talk shows how to take your React Native delivery pipeline to the next level.
