I will develop custom mobile app with API and backend integration


About this gig
Have an Android app idea that needs more than just a few screens?
I build custom Android applications with a strong focus on clean UI, real functionality, and reliable backend integration.
I can help you build:
- Custom Android apps
- Business & service apps
- Login and user accounts
- API & database integration
- Firebase features
- Push notifications
- Maps, GPS & location features
- Payment integration
- Dashboards and user flows
- Admin/backend connectivity
- Existing app improvements
- Bug fixes and new features
Im a Full-Stack Developer & Vibe Coder, so I can handle more than the mobile interface. I can connect your app with APIs, databases, authentication, dashboards, and backend systems when needed.
My workflow uses AI-assisted development to move faster, while I still review the logic, UX, performance, security, and final functionality myself.
You can send me a Figma design, reference app, existing codebase, or even a rough idea.
For complex apps, message me before ordering so we can define the right scope.

FAQ
Can I contact you if I only have an app idea?
Yes. You can send me a rough idea, reference app, sketch, or Figma design. I can help turn it into a realistic feature list and development scope.
Do you build the backend too?
Yes. I can connect the Android app to APIs, databases, authentication, admin dashboards, and backend systems depending on your package and project requirements.
Can you add maps, GPS, or location tracking?
Yes. I can implement maps, GPS, location-based features, route tracking, and related integrations when required.
Can you work on an existing Android app?
Yes. I can continue an unfinished project, add new features, improve the UI, integrate APIs, fix bugs, or improve existing functionality.
Will I receive the source code?
Yes. Source code is included according to the selected package so you can maintain or continue developing the app later.
Can you publish the app to Google Play?
Yes. I can assist with preparing and submitting the app to Google Play Console. The developer account should remain under your ownership.
Do you use AI or vibe coding?
Yes. I’m a Full-Stack Developer & Vibe Coder. I use AI-assisted development to speed up parts of the workflow, while still reviewing the logic, UX, security, performance, and final functionality myself.
What if my app is more complex than the Premium package?
For apps with advanced GPS, real-time features, multiple user roles, complex payments, large backend systems, or many screens, message me first and I’ll prepare a custom offer based on the actual scope.
