💻 Speakers
📣 Dawid Matyjasik
(Software Engineer @ Software Mansion)What Really Happens When a React Native App Starts?
What happens between tapping the app icon and seeing the first React Native screen? In this talk, we'll trace the startup process step by step, from native initialisation and JavaScript runtime setup to loading the bundle, creating the React tree, and rendering the first frame.
📣 Joel Sebastian
(Software Engineer @ Runna)The 200MB Cliff
200MB is the number where users stop downloading your app. We kept hitting it. Here's how we stopped - and the guard rail we lost on the way down.
📣 Hassan Khan
(Software Engineer @ Expo)Expo on Expo Router and Web
