About this gig
Need a cross-platform mobile app for iOS and Android?
I build React Native and Expo applications with TypeScript, clean architecture, responsive mobile UI, API integrations, authentication, data storage, and production-ready builds.
I can help you create a custom mobile app, MVP, education app, restaurant app, productivity tool, customer portal, or other cross-platform product.
What I can build:
- React Native / Expo applications
- iOS and Android from one codebase
- Authentication and user roles
- REST API and backend integrations
- Supabase and database-backed apps
- Push notifications
- Navigation, forms, profiles and data screens
- Custom responsive mobile UI
- Expo / EAS build and release setup
I focus on maintainable TypeScript code, reusable components, performance, security, and a smooth user experience across devices.
For larger apps or custom MVPs, please contact me before ordering so we can define the scope, timeline, integrations, and milestones.

FAQ
Do you build for both iOS and Android?
Yes. I use React Native and Expo to build cross-platform applications for both iOS and Android from one shared codebase.
What do you need from me before starting?
Please provide your app requirements, main features, design or references if available, backend/API information, and any existing project files or repository access.
Can you build an app from scratch?
Yes. I can build a new React Native / Expo application from an idea, specification, wireframe, or Figma design.
Can you integrate an existing backend or API?
Yes. I can connect the mobile app to REST APIs, authentication services, databases, and existing backend systems.
Can you add authentication and user roles?
Yes. I can implement login, registration, protected screens, role-based access, and different user flows depending on the app requirements.
Do you work with Supabase?
Yes. I can use Supabase for authentication, database access, storage, and backend functionality when it fits the project.
Can you add push notifications?
Yes. I can integrate push notifications in React Native / Expo applications. This can be included in the package or added as an extra depending on the scope.
Will I receive the source code?
Yes. The complete source code for the delivered work is included in all packages.
Can you publish the app to the App Store and Google Play?
I can prepare the app for release and help with submission. Final approval is handled by Apple and Google and cannot be guaranteed.
What if my app is larger than the Premium package?
Please contact me before ordering. I can review the requirements and create a custom offer with the correct scope, price, timeline, and milestones.
