What if you could skip most native builds—and still ship confidently? In this episode of React Universe On Air, we explore how the React Native Enterprise Framework (RNEF) helps large teams dramatically reduce build times and streamline development at scale.

Our guest Michał Pierzchała, Principal Engineer at Callstack, shares how RNEF was built to solve real-world bottlenecks in enterprise React Native projects. Alongside him, Łukasz Chludziński discusses his experience testing the framework in a live production environment, where build times dropped from 35 minutes to just 3.

What you'll learn:- How RNEF slashes native build times with CI-based caching- Ways to adopt the framework incrementally—no full rewrite required- How brownfield support lets you drop React Native into native apps easily- What makes RNEF different from Expo and Community CLI- Real-world savings and improved developer-QA workflows
