I will build your custom flutter firebase app for android ios app with auth database
Faith T
About this gig
Building a Flutter and Firebase app should feel straightforward, not like guesswork. I build Android and iOS apps from one codebase, wire up Firebase Authentication and Firestore so your data and user accounts just work, and connect any APIs your app needs to talk to.
Most clients fall into one of three situations:
- A founder validating an idea and needing a working MVP fast
- A business owner who needs a clean admin panel and backend behind their app
- Someone whose existing app has features that don't quite work yet and needs them finished properly.
I handle the full stack:
- UI built from your designs or a clean default if you don't have any
- Secure login and user accounts
- A Firestore database structured the way your app actually needs it
- Push notifications that reliably reach users
- Deployment support when you're ready to publish.
- Everything is built with clean, readable code so a future developer, or future you, can maintain it.
Send me a short description of what you're building and I'll tell you honestly what's involved and roughly how long it'll take before you spend a cent.

I am a Flutter mobile app developer focused on building clean, responsive, and scalable Android and iOS applications for startups, businesses, and personal brands. I work with Flutter, Dart, Firebase, REST API integration, bug fixing, push notifications, payment integration, UI implementation from Figma, and app publishing support. My goal is simple: stable code, smooth user experience, clear communication, and on-time delivery for every project.
FAQ
Do you build for both Android and iOS?
Yes, Flutter compiles to both from one codebase, so you get feature parity without paying for two separate builds.
What if I already have a partly built app?
Send me what you have and I'll review it honestly, then tell you whether finishing it or rebuilding the broken parts makes more sense.
Do you set up the backend too, or just the app?
Both. Firebase Authentication, Firestore, and any API connections are included, so you're not left needing a second developer.
Can you design the UI, or do I need to provide one?
I can work from your Figma file or existing design, or build a clean, simple UI from scratch if you don't have one yet.
How do push notifications work in my app?
I set up Firebase Cloud Messaging so users get notified reliably, tested on real devices before delivery.
What do you need from me to start?
A short description of what the app should do, any design files you have, and access to your Firebase project if one already exists.
Will I get the source code?
Yes, full source code is included in every package so the app is genuinely yours.
Can you help me publish to the App Store and Google Play?
I can prepare the build for submission; publishing itself needs your own developer accounts, which I'll guide you through.
What if my app needs a feature you didn't quote for?
I'll flag anything outside the original scope before starting it, so there are no surprise costs.
How long does a typical build take?
Depends on scope. A simple MVP takes about a week; a fuller app with a custom backend usually takes longer. I'll give you a real timeline after hearing what you need.
