Mobile App Developer for Fitness & Health Apps

I'm looking for an experienced mobile app developer to help add 3–4 new screens to my existing fitness and health app. The app is already live/in development, and I need someone who can seamlessly integrate the new screens while maintaining the current design and user experience. The ideal candidate should have experience working with mobile apps, be comfortable with existing codebases, and have a good eye for clean and intuitive UI/UX. Experience with fitness, health, wellness, or lifestyle apps is a plus. Some screens may require API integration and connecting with existing app functionality. Please apply with a brief introduction, relevant experience, examples of similar apps you've worked on, your preferred tech stack (Flutter, React Native, iOS, Android, etc.), and your estimated timeline for completing the task.
