I’m looking for a talented solo React Native iOS developer with strong Figma and UX/UI design skills to turn an existing GPT-generated mockup into a polished production app. React Native iOS, Firebase, Figma, and UX/UI design experience are mandatory. If you don’t have real experience with all four, please do not apply. You must be able to review the mockup, improve the UX, user flow, persona, and visual design in Figma, then implement the final design in React Native, integrate Firebase and sports APIs, test, and deploy the app to the App Store. This is a sports analytics app, so experience with U.S. basketball, sports analytics, sports apps, or sports APIs is a strong plus. In your proposal, provide ONE iOS app you personally developed and successfully deployed to the App Store that you are genuinely proud of, including the design and a brief explanation of your contribution. I carefully review every proposal, so please do not waste your time applying if you are not a strong fit or do not have proven experience with React Native iOS, Firebase, Figma, and UX/UI design. I’m looking for a talented individual, not an agency. Solo developers only. You must be available to work during EST time zone hours and commit full-time for the next 3 weeks. Budget: $1,500 total, milestone based.

Hi — Elias here from Miami. I see you're looking for a React Native developer who can also handle UX/UI design for a sports analytics app. The goal is to create a seamless user experience while leveraging Firebase for backend functionality. What usually matters most here is ensuring that the app is both scalable and maintainable. A common issue in systems like this is managing state effectively, especially as user interactions increase. The tricky part is usually integrating the design from Figma into a responsive application. My approach would involve setting up a solid architecture that separates concerns, allowing for easy updates and future enhancements. I’d prioritize performance and ensure the app can handle a growing user base without issues. I’ve worked on similar projects, focusing on integrating complex workflows and utilizing Firebase for real-time data management, which highlights the importance of a robust backend. A few questions to better understand the scope: Q1 – What specific user roles and permissions will the app have? Q2 – How do you envision the integration with Firebase for data management? Q3 – Are there any specific features in the Figma design that you anticipate may pose challenges during development? Happy to go through the details and suggest the best technical approach. Looking forward to hearing from you.

Hello! As per your project post, you are looking for a solo React Native iOS developer who can take an existing GPT generated mockup, improve the UX and UI in Figma, implement the polished design in React Native, integrate Firebase and sports APIs, and take the app through testing and App Store deployment. The main focus is turning the current concept into a refined, production ready sports analytics experience rather than simply coding the existing screens. I can help with the complete flow from Figma review and UX improvements through React Native implementation, Firebase integration, sports data integration, testing, optimization, and App Store submission. I will focus on making the user journey clear, improving the information hierarchy for sports analytics, and ensuring the final interface remains responsive and easy to use on iOS. I have experience with React Native, Firebase, Figma based implementation, API integrations, and mobile app development, and can take ownership of the product from design refinement through deployment.
