I’m looking for a seasoned React Native developer to help me update an existing application by introducing new features. The core codebase is stable, but I now need extra functionality layered in without disrupting what already works. Here’s what I expect: • Plan and propose the best way to integrate the requested features while keeping the current architecture intact. • Write clean, well-commented React Native code and accompany it with any necessary updates to Redux, navigation and API interfaces. • Test the additions thoroughly on both iOS and Android, fixing any regressions you encounter. • Hand over concise release notes and a short “how-to” for maintenance. If you’ve recently shipped feature upgrades in production React Native apps, especially those involving complex component trees, I’d love to see your work.
