Through practical examples, you'll see how to build highly flexible form experiences while keeping your codebase clean, maintainable, and scalable. 19:20 React Native at Scale — Lessons from building Hevy Speaker: Batuhan Demir, Full Stack Developer at Hevy Our journey from MVP to 14M+ users, covering how we navigated the cross-platform tradeoffs of React Native, how we use React on the web side too, what we'd do differently, and what's to come next 19:50: Drinks and networking! 20:45 Meetup finished Would you like to talk at the next meetup?
