During October 2025, Tomasz Sapeta enhanced image processing capabilities across the expo/expo and facebook/react-native repositories. He delivered HDR image support for iOS by introducing a new ImageHDRScreen and integrating a high dynamic range toggle, leveraging Swift and TypeScript to utilize iOS 17+ features. Tomasz also initiated Swift 6 adoption in Expo modules, updating CocoaPods configurations to enforce safer concurrency. In facebook/react-native, he optimized large image decoding in RCTImageLoader by replacing thumbnail-based decoding with full-sized image handling, reducing memory usage and improving stability. His work focused on performance, maintainability, and modernizing the iOS image pipeline.
