In this talk from Callstack’s React Universe Meetup in San Francisco, Michał Pierzchała ( https://x.com/thymikee ), Principal Engineer at Callstack, introduces the React Native Enterprise Framework (RNEF)—an open-source framework designed to make native builds faster, smarter, and cheaper for teams working at scale.

Watch Michał walk through how RNEF cuts CI build times by up to 90% using remote caching. You’ll see how Expensify went from 30-minute iOS builds to near-instant results—without switching CI providers or giving up control.

This talk covers:
- Native build fingerprinting that actually works
- Reusable artifacts across CI, dev, and test environments
- GitHub Actions integration for artifact caching
- Modular CLI design for real-world enterprise constraints
- Brownfield support for easy incremental adoption
