Marcos Carrera
About this gig
Need a professional mobile app for iOS and Android?
I will turn your idea, Figma design, or existing concept into a functional cross-platform mobile application using React Native, Expo, and TypeScript.
I can build MVPs, business apps, booking platforms, social apps, dating apps, ecommerce apps, educational apps, and custom mobile solutions.
What I can include:
- iOS and Android development
- User authentication and profiles
- Firebase or Supabase backend
- Database integration
- REST API integration
- Push notifications
- Payments and subscriptions
- Real-time features
- Responsive UI implementation
- AI integrations
- App Store and Google Play preparation
- Complete source code
I focus on building clean, reliable, and scalable applications that can grow with your business.
Already have a Figma design? I can turn it into a functional app. Have only an idea? I can help structure it into an MVP and define the features needed for the first version.
Please contact me before ordering so I can review your requirements and recommend the right package for your project.

FAQ
Do you develop apps for both iOS and Android?
Yes. I build cross-platform mobile apps with React Native, allowing your application to run on both iOS and Android from a shared codebase.
Can you build an app from just an idea?
Yes. If you only have an idea, send me the main features you need. I can help organize the requirements and define a practical MVP before development.
Can you work from a Figma design?
Yes. If you already have a Figma design, mockup, or reference app, I can turn it into a functional React Native application.
Will I receive the source code?
Yes. You will receive the complete source code for all development included in your order.
Do you build the backend too?
Yes. I can build or integrate a backend using Firebase, Supabase, Node.js, REST APIs, or connect your app to an existing backend.
Can you add payments, notifications, chat or AI?
Yes. I can integrate features such as payments, push notifications, real-time chat, maps, external APIs, OpenAI/AI services, and more. Complex features may require an additional quote.
Can you publish the app to the App Store and Google Play?
Yes. I can prepare and assist with the submission process. You will need your own Apple Developer and Google Play Developer accounts. Final approval is determined by Apple and Google.
What do you need from me to get started?
A description of your app, required features, design files if available, reference apps, and any existing API or backend information. If you don't have everything ready, contact me and we can define the requirements first.
Which package should I choose?
It depends on your app's complexity. Basic is intended for small apps or prototypes, Standard for functional apps with backend features, and Premium for more complete MVPs. Contact me before ordering if you're unsure.
Should I contact you before placing an order?
Yes, especially for custom apps. Send me your requirements first so I can review the scope, timeline, and recommend the right package or create a custom offer.
