Experienced Mobile App Developer Needed to Fix App Issues & Implement New Updates

We are looking for a skilled mobile app developer to fix critical bugs and add new features to our application. Currently, the app is facing performance issues that need immediate troubleshooting: frequent crashing/freezing during usage, slow screen loading times, UI/UX layout glitches on different screen sizes, and high battery drainage. You will be required to analyze the existing codebase, identify the root causes of these performance bottlenecks, and deliver clean, optimized, and bug-free code. In addition to bug fixing, we want to implement several new feature updates and enhancements to improve the overall user experience. To be considered for this role, please share your previous mobile app development portfolio, mention the frameworks you specialize in (e.g., Flutter, React Native, Swift, or Kotlin), and explain your approach to debugging. We prefer a developer who communicates clearly, respects deadlines, and can write scalable code for long-term app maintenance.
