About this gig
Android app development with Flutter and Firebase one codebase for Android and iOS, published on Google Play.
I'm Oscar. 30+ apps delivered for clients in the US, UK, Spain and Latin America. I work in English and Spanish.
What I build:
- Android apps in real Flutter code (not no-code builders)
- Firebase: authentication, Firestore, storage, push notifications
- Delivery, e-commerce, marketplace, booking, inventory and social apps
- REST API and third-party integrations
- Figma to Flutter, pixel-perfect
- Google Play publishing, plus App Store if you need iOS
How I work:
The project runs in fixed phases. At the end of each phase you get a testable APK, and you only pay once you approve it. No upfront payment.
Always included: source code, 30 days of support, and written updates you can actually follow.
Send me a message with your idea before ordering and I'll come back with a scope and a fixed price.

FAQ
What do you need to get started?
Just your app idea and any references or features in mind. We define the scope together before you order that's why I ask you to message me first.
Do you build native or Flutter apps?
I build with Flutter, so you get one clean codebase for both Android and iOS — faster to build, cheaper to maintain, with a native look and feel.
Do you design the app too?
Yes. Design and development come together a professional UI/UX so your app looks as good as it works.
Do you charge upfront?
No. I work in phases and deliver a testable APK at the end of each one. Fiverr holds the payment and releases it only after you approve.
Will I get the source code?
Yes, full source code is included in the Standard and Premium packages.
Can you publish my app to the Play Store?
Yes Play Store submission is included in Standard and Premium (you'll need a Play Console account), or I can guide you through it.
What if I need changes or a bigger app?
Each package includes revisions and I offer ongoing support. For larger, multi-phase apps I send a custom milestone-based offer.
