The Story

New Meetup is here! Let's gooo! We have some amazing speakers, and pizza and beer will be available after the event. ────────── **18:00: Welcome** Grab a beer, a snack, and a seat until everybody arrives! **18:30 Intro by Host Neciu Dan** **18:45 Building Multi-Step Form Experiences in React: Onboarding, Surveys, Checkout & More** Speaker: [Martí Serra Molina](https://www.linkedin.com/in/martiserramolina/), Creator of Formity In this talk, I'll introduce Formity, an open-source React library that treats multi-step forms as programmable flows instead of static sequences of steps. We'll explore how describing the user journey declaratively makes complex experiences easier to build, reason about, test, and evolve. 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](https://www.linkedin.com/in/batuhan-demir-10b1b3154/), 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?
