Hello! I have extensive experience in optimizing React Native applications, particularly with Expo. I've successfully tackled performance issues similar to yours, ensuring smoother transitions and overall better user experiences. In a recent project, I worked on a shopping app where I resolved lagging transitions and improved list scrolling performance. This involved analyzing the navigation stack and optimizing image loading, which resulted in a significant boost in responsiveness. For your project, I plan to start by profiling the app using tools like React Native Performance Monitor to identify bottlenecks in navigation and rendering. I'll focus on optimizing list rendering techniques and implementing efficient image loading strategies to ensure smooth scrolling. Additionally, I will ensure that all transitions and animations run at 60 FPS by fine-tuning the animations and leveraging libraries that enhance performance. I would love to discuss this project further and share more about my approach. Best regards, Inderdeep

Hi, I specialize in performance tuning for React Native & Expo apps, and I’ve solved the exact issues you’re facing — laggy transitions, frame drops on scroll, and unoptimized image carousels. - Optimization Strategy: Diagnose via React DevTools & Flipper to pinpoint JS thread bottlenecks and re-renders. Replace heavy FlatLists with FlashList from Shop ify where needed for large datasets. Use react-native-reanimated for smooth 60 FPS screen transitions. Lazy-load and cache images with expo-image, optimized for memory usage. Profile the app using Expo’s Performance Monitor + Hermes insights. - Real Case: In a marketplace app with 5,000+ product entries and image galleries, I reduced list scroll frame drops from 18 to <2 per second using FlashList, memoized components, and on-demand thumbnail resolution. Let’s get your app running butter-smooth on all devices. I’ll start with a performance audit and deliver fixes in clean, modular commits. Looking forward, Oleg | React Native Performance Specialist
