On January 29, 2026, Zalando is teaming up with Callstack to host an in-person React Universe Meetup. Expect an evening built for experienced engineers who care about how things actually work in production, with time for both focused talks and unstructured conversations. The event is aimed at software developers, senior engineers, and architects working across full-stack and cross-platform applications, with an emphasis on sharing practical lessons, architectural tradeoffs, and production-ready approaches. It’s a space for teams working with React Native and related technologies to compare notes, learn from peers, and take ideas back to their own codebases. **Important: In order to attend this event, please register on the [Callstack event page](https://www.callstack.com/events/react-universe-meetup-x-zalando-berlin).** ## Agenda * **6:00 PM** Doors open * **‍6:20 PM** Welcome * **‍6:30 PM** Building a Video Experience with React Native: Lessons from Early Adoption Speaker: Eugene Verichev, Zalando * **6:55 PM** LLM inference on-device in React Native: the practical aspects‍ Speaker: Artur Morys-Magiera, Callstack‍ * **7:20 PM** Talk 3 (details to be announced)‍ * **7:45 PM** Q&A‍ * **8:00 PM** Networking Additional talks and speakers will be announced closer to the event.
