I’ve been passionate about technology since childhood, starting with electronics and embedded systems (a long time before Arduino was a thing). I graduated in Automation and Robotics but ultimately found my calling in web development. With over 10 years of professional experience, I’ve spent the last 3 years at Klarna as a member of one of the Client Core teams. We focus on the foundations of the Klarna RN application, building tools and infrastructure that serve tens of millions of users worldwide.

One of the greatest advantages the web has over native apps is the ability to ship updates instantly. React Native’s Over-The-Air (OTA) feature promises similar agility—but is it really that simple?

In this talk, I’ll explore the challenges, pitfalls, and successes involved in creating a robust OTA solution from scratch. Drawing on our experience at Klarna—where we serve tens of millions of users—I’ll show you the essential architecture, tooling, and strategies needed to reliably deliver updates outside the native release cycle. If you are considering implementing OTA in your project—even with ready-made solutions like CodePush or Expo over-the-air updates—you’ll benefit from this talk by gaining a deeper understanding of the hidden complexities behind such tools.

Zack is a Module Federation Core team member, ByteDance innovator, Rspack contributor and Tauri board member. With deep architecture and development experience with enterprises of global scale he brings the experience of real world enterprise experience to the stage. As a startup founder he also brings the reality of scaling from 0 to 1.

When it comes to releasing new versions of your app its pain at almost every stage. This pain becomes worse as our teams grow with constant merge battles, releases, and rollbacks. What if there was a better way?

With the release of Re.Pack 5 there is support now in React Native for Module Federation.

With millions of downloads a week the de facto standard for distributed web development is now available for mobile.In this talk we will explore:
1) How to decompose our mobile applications into multiple modules
2) Why we would want to give our teams independence and different release velocities
3) How to version and release these versions independently in practice
4) A comparison of tools on the market to manage over the air updates
5) Strategies on how to test in production while maintaining instant roll backs

React Native library that provides a framework that re-enables RN's existing Systrace JS API from the native code (Nitro Modules), providing a plugin system that allows plugging in an arbitrary native tracing backend into it.

Richard Hipp is the creator and lead developer for SQLite, the most widely deployed database engine, and perhaps the most widely deployed software of any type, in the world today. He also works on other open-source projects such as Fossil and Pikchr

Head of Mobile at Vercel. Previously co-founder of BeatGig, a marketplace for booking live music. Prior to BeatGig, Fernando's startup was part of Y Combinator's W19 batch. While in college at UPenn, he founded PATOS Shoes – a sneaker brand that sold in over 15 countries, and was featured in J. Crew, Forbes, Buzzfeed, NBC, and more. Rojo is the maintainer of many open source React libraries, including Solito, Moti, Dripsy, Zeego, and Burnt.

Software Engineer working on the Hermes compiler and VM for the last 5 years.

Xuan is a software architect on the Lynx family of technologies, where he can dream of making interfaces better for more users, more developers, and more machines. Before joining ByteDance, he worked on React Core ("React Forget"), React Native, Hermes and Reason during his time at Meta.

With a passion for creating seamless cross-platform experiences, my journey in tech started not with programming, but as a consultant in the tech industry. The desire to build and innovate led to a shift in focus towards software development, particularly mobile app development, where the thrill of solving complex problems and crafting user-friendly applications became a calling. Co-founding Frontend Queens was a natural extension of this journey, inspired by a commitment to inclusivity in tech. This community was born from the belief that everyone, especially women, should have the opportunity to thrive in technology. By fostering a supportive environment, we aim to empower women to break barriers and pursue fulfilling careers in this ever-evolving field.

Is your app built on guesswork, or do you have data to back up your decisions? In this talk, we'll dive into A/B testing in React Native and how we at ClipMyHorse.TV use experimentation to optimise our app. Learn how to design and implement meaningful tests, analyse results, and shift from intuition-based development to data-driven decision-making.

The Node API is an API for building native add ons for Node.JS. It is JS Engine agnostic, and ABI stable, which makes it very versatile and what allows alternative runtimes like Deno and Bun to target Node compatibility. In React Native Windows, we have maintained a fork of Hermes that reimplements JSI on top of the Node API. We have been working with the community to bring this integration to the rest of React Native. Come learn more about what this unlocks, and how much farther you can take your app with the full power of both Hermes and Node-API together!

He's main contributions has been to the Realm JS SDK, Realm Studio (data browsing Electron / React app) and the React frontend for the (now deprecated) Realm Cloud.Kræn lives 30 minutes west of Copenhagen, with his wife and their two 4 year old twin girls. They recently added yet another newborn girl to their pack.

Dr. Küçük is a computer scientist who spent 10 years at Oxford University in various research positions focusing on systems security. He is the author of the “Confidential Remote Computing” paradigm and previously received grants from Intel Corporation for his TEE-related work. Previously, he was a research engineer at ETH Zürich, delivering C++-based industrial software products in the areas of Industry 4.0, simulation, and digital twin technologies. Alongside his teaching activities at Oxford, he is currently exploring independent opportunities.

Although C++ offers a wide range of computational libraries with various capabilities and enables high-performance computing, there are long-standing challenges in integrating them into a React Native project. To address these challenges, we developed a practical set of tools and a sustainable methodology for automating an all-in-one solution for using C++ libraries in cross-platform JavaScript applications.

Manually compiling, porting, and bridging a library is not only difficult but also unscalable in enterprise settings. For large corporations and commercial products, using C++ in React Native should not introduce additional complexity or make projects fragile. Instead, the React Native community needs a stable, permanent, long-term solution that works in a scalable manner while offering reliability.

With cpp.js, developers can include many pre-ported C++ libraries into React Native or WebAssembly projects by simply including the relevant header files. While the Codegen project already supports C++ bridging in React Native, it is limited to function calls and primitive types. In contrast, we offer Object-Oriented Programming (OOP) support and modern C++ features (C++11 & C++14), enabling integration with a broad range of widely-used C++ libraries. For example, we have successfully integrated GIS libraries such as GDAL into React Native, demonstrating cpp.js’s practical effectiveness. With little to no effort, cpp.js can support the long-term maintenance of various C++ libraries, thanks to our automation processes. This minimises the traditionally difficult engineering work of cross-compiling, porting, and bridging libraries to JSI.

Following the introduction to our toolset, architectural decisions and development journey, we will show;

(1) how to quickly write and execute native C++ code within a JavaScript environment,

(2) utilising and importing ready-to-use native C++ libraries from our cpp.js repository. Further, for developers in more sophisticated cases,

(3) we will show how to port a C++ library you need using our toolset, even if the C++ library has external dependencies. This showcases modularity, independence in maintenance, the scalability characteristics of our project, further giving developers more control.

We warmly welcome collaboration and feedback from the React Native community. Although this talk focuses on React Native, cpp.js is a cross-platform solution that also supports WebAssembly (web, Node.js, Cloudflare Workers, etc.), alongside mobile platforms. We will cover these broader aspects in our upcoming talks.
