React Native Developer & Mobile UI/UX Expert

We are looking for an experienced React Native developer with strong mobile UI/UX skills to improve and expand an existing mobile application. The app is already live on the App Store. The immediate focus will be modernizing the interface, improving usability, resolving existing UX issues, and creating a more polished and consistent experience across the app. We also plan to introduce new features over time. This is not a project that requires rebuilding everything from scratch. We need someone who can review the current codebase, understand the existing product flow, recommend practical improvements, and implement them without disrupting current functionality. REQUIRED EXPERIENCE * Strong professional experience with React Native * Proven mobile UI/UX implementation experience * Experience improving or modernizing an existing mobile application * Comfortable working with Firebase * Experience with subscription-based mobile applications * Strong understanding of reusable components and scalable architecture * Experience debugging mobile application issues * Clear written and verbal communication * Ability to work independently and provide thoughtful recommendations The first phase will focus on reviewing the current application, identifying the most important UI/UX and technical improvements, and implementing the agreed priorities. We are planning to develop several similar applications, so this project has strong potential to become a long-term working relationship for the right developer. TO APPLY PLEASE INCLUDE: 1. Examples of React Native applications you have built or improved 2. Links to relevant App Store or portfolio projects 3. Your approach to reviewing and modernizing an existing mobile app 4. Your availability and expected weekly capacity 5. If you're a real person, not AI, please begin your proposal with the words “Mobile App.”
