When building apps with strict security requirements, developers often default to fully native or brownfield approaches, assuming that JavaScript-based solutions fall short. However, times have changed—many of the security blockers that once limited React Native have been overcome, allowing greenfield apps to achieve the same level of security as their native counterparts.

But security isn’t automatic. Developers must still take deliberate steps to safeguard their apps. By leveraging Expo modules, we can implement critical security features such as secure storage, encrypted networking with TLS pinning, and host whitelisting. Additionally, advanced protections like device assurance, runtime security, and threat monitoring play a crucial role in keeping our apps safe against modern threats—yet many React Native developers remain unfamiliar with them.

In this talk, we’ll explore the essential security technologies available to React Native engineers, demystify key security concepts, and showcase how you can build truly secure mobile applications—without sacrificing the benefits of React Native.

Let's be honest, nowadays most of us see an error, copy it into ChatGPT, and hope for the best. I've done it. You've done it. We've all wasted 30 minutes going back and forth with AI when our browser could've shown us the answer in 2 minutes.

This talk is about remembering that our browsers have incredible debugging tools we've forgotten how to use. Through live demos of real bugs, I'll show you how breakpoints, call stacks, and the network tab can solve problems maybe faster than any AI assistant.

You'll learn:

• How to ditch console.log hell and actually watch your code run
• Breakpoint tricks that pause your app so you can inspect what's really happening
• How to read call stacks without your eyes glazing over
• Network tab techniques that expose exactly why your API is misbehaving
• When debugging tools beat AI (and when AI is actually helpful)
 I'm not saying don't use AI—I use it all the time. But there's something powerful about understanding your own code well enough to fix it yourself. Plus, you'll be way faster, and you'll actually learn something instead of just copy-pasting solutions you don't understand.

An in-depth look at Static Hermes, the next iteration of React Native’s JavaScript engine. Learn how it impacts performance, what you can do with it today, and what’s coming next.

CI setup for a new React Native project is a tedious trial&error process. Let’s talk about how we can make it simpler.
