18:45 Intro by Host Neciu Dan

19:00 Kibble: Designing Hybrid Components for Native and Web
Speaker: Traian Stanciu Senior Software Engineer at Rover.com

Building a component library that runs on web, React Native, iOS, and Android without diverging into chaos is harder than it sounds. This talk digs into how Kibble—Rover's design system—handles the gap between platforms through a file-naming convention (`.tsx` / `.native.tsx` / `.common.ts`), a unified event abstraction that bridges web click and native press events, and a token pipeline that generates Swift, XML, CSS, and TypeScript from a single source of truth

19:25 React Native in a Native App: Brownfield Integration & Over-The-Air Deployments
Speaker: Luca Barone Mobile Engineer at Rover.com

A practical look at how Rover.com ships React Native screens inside fully native iOS and Android apps — without rewriting them from scratch. We'll cover the "brownfield" integration pattern, how JS and native code communicate through bridge modules, and how we deploy JavaScript updates to users in minutes using Expo EAS Update, completely bypassing the App Store review cycle.

19:50: Drinks and networking!
