What if 90% of your React Native builds didn’t need to be built at all?
In this recorded webinar, Mike Grabowski (CTO at Callstack, https://x.com/grabbou) and Michał Pierzchała (Principal Engineer at Callstack, https://x.com/thymikee) walk you through how Callstack’s recently open-sourced React Native Enterprise Framework (RNEF) makes that possible.
You’ll see how Expensify used RNEF to reduce debug build times from 40 minutes to 2 minutes, without switching CI providers or sacrificing control.
With a live demo, real GitHub Actions pipelines, and concrete cost comparisons, this session gives you a practical look at native build caching that works across local dev, CI workflows, and end-to-end tests.
What you’ll learn:
🟣 How to avoid native builds 90% of the time using smart fingerprinting
🟣 Why typical caching setups fail—and how to fix them
🟣 How RNEF brings modularity, flexibility, and speed to large-scale React Native projects
🟣 How to incrementally adopt the framework in existing Community CLI projects
Whether you're stuck waiting on CI or scaling a growing React Native codebase, this webinar shows you how to ship faster, without paying more.
