I need a reliable React Native developer to get my existing mobile app back into shape. The current build sits on an older React Native version and now throws crash-related bugs that block release. The work is straightforward: • Upgrade the project to the latest stable React Native version, taking care of any breaking changes. • Eliminate the crashes/bugs that appear in the present build so the app runs smoothly again. I will provide the full codebase and recent crash logs. Please focus only on what is necessary to compile and run the app cleanly—no new features or design work are required at this stage. Deliverables are: 1. Updated source code that builds without errors on Android and iOS simulators. 2. A concise changelog outlining the key upgrade steps and fixes applied. 3. Brief setup notes so I can reproduce the build on my machine. If you’ve handled React Native version jumps and stubborn crash fixes before, I’d love to hear how quickly you can turn this around. Current Apps Version: "react": "18.1.0", "react-native": "0.70.5",
