I will build your react native expo app for ios and android
Uros Z.
About this gig
I build cross-platform mobile apps for iOS and Android using React Native, Expo and TypeScript.
I can take your app from idea and requirements through UI implementation, authentication, Supabase backend, API integrations, testing and store-ready delivery.
Typical projects include booking apps, business tools, productivity apps, sports platforms, customer portals and custom mobile products.
My focus is on building clean, reliable apps with real business logic not just static screens or prototype demos.
Depending on the project, I can implement authentication, databases, user roles, API integrations, push notifications, deep linking, secure data handling and release-ready builds.
You receive clean source code and a solution designed around your actual workflow.
For larger apps, multiple user roles, advanced integrations or App Store / Google Play submission, please message me before ordering so I can recommend the right scope and package.

FAQ
Will the app work on both iOS and Android?
Yes. I use React Native and Expo to build one shared codebase for both platforms while adapting the experience where platform-specific behavior is required.
What do you need from me to get started?
I need your app idea, target users, required screens, core features and any existing designs or references. For larger projects, please contact me before ordering.
Can you build authentication and a backend?
Yes. I can implement authentication, user accounts, database functionality and permissions using Supabase, depending on the package and project scope.
Can you connect the app to external APIs or services?
Yes. I can integrate third-party APIs and supported services when documentation and access are available. Additional integrations may require a Gig Extra or custom offer.
Can you submit the app to the App Store and Google Play?
Yes, submission assistance can be included in the Premium package or added separately. Submission is done through your developer accounts. Final approval is always controlled by Apple and Google.
Do I receive the source code?
Yes. Source code is included in every package so you retain control of the application and can continue developing it in the future.
