React Universe Meetup is back in the US, and this time we’re landing in New York City at [The Farm Soho](https://maps.app.goo.gl/JD19PqufVZe3vubM7). We’re joining forces with [Embrace](http://Www.embrace.io) to bring you a packed evening of cutting-edge insights, real-world case studies, and practical tips for building better cross-platform apps.

## Who's this meetup for?

If you're building with React Native, scaling full-stack mobile apps, or figuring out how to ship and observe complex deployments, this meetup is for you.

You’ll be in good company with engineers, app architects, and folks who care deeply about performance, code quality, and real-world trade-offs. Expect solid talks, sharp minds, and good vibes. No fluff, just practical insights and time to connect with other people who get it.

## Agenda

**6:00 PM** – Doors open, grab a slice

**6:30 PM** – _Intro: Welcome to React Universe Meetup_ by Mike Grabowski, CTO & Founder at Callstack and Andrew Tunall, President at Embrace

**6:40 PM** – _Observability for Application Deployments_ by Pepijn Senders, Principal Software Engineer at HelloFresh

How does one prove that rendering dependencies are slow? In this talk, I’ll share how we used observability to build a data-driven case for improving end-to-end network performance. By tracing latency across the stack, we uncovered hidden bottlenecks and shifted the conversation from assumptions to evidence.

**7:05 PM** – _Elevate your React Native observability with OpenTelemetry_ by David Rifkin, Developer Relations at Embrace

In this talk, David Rifkin from Embrace, the user-focused observability company, will talk through why production data matters for mobile and frontend engineers. He will discuss:

- What OpenTelemetry is (briefly, he promises) and how it helps developers collaborate across teams
- The complexity of mobile observability, and how to use it to build more resilient apps
- How React Native engineers can make sense of the JS/native gap in production

**7:30 PM** – _Brownfield Incremental React Native Adoption x Rock_ by Michał Pierzchała, Principal Engineer at Callstack

Adding React Native to existing native projects is hard today, involving a lot of moving code around, adding legacy tooling (CocoaPods) and making native engineers familiar with [Node.js](http://node.js/) ecosystem. In this talk we'll go through a modern way of integrating React Native into a sample iOS and Android apps, utilizing \`react-native-brownfield\` library and Rock, which makes the whole process easier and less disruptive for iOS and Android developers.

**8:00 PM** – Networking
