Flutter App Backend Reconfiguration

Job ID: 39650253

Budget: $30 – $250 USD

Hi, I’m looking for a skilled Flutter + backend developer.
I have a live sports app built with Flutter. Currently, all API requests are handled directly inside the Flutter code. I want to move all API logic to a backend server (Node.js or Python) and connect Flutter only to that backend.

Here’s what I need:

What I want:

Move current API calls (used in 10–20 screens) to a backend proxy

Add a second API as fallback, used when the primary fails

Use caching on the backend (because of 1 request/second limit)

Make the primary API switchable via Firebase Remote Config or a similar method

Ensure all features currently depending on the first API continue to work identically with either API

The app should remain stable and crash-free (ANR/crash already optimized)

I don’t want to remove the first API, just make it manageable and controlled from the backend

API types involved:
The data includes:

Live match details

Team information

League/tournament data

Standings

Fixtures

Logos and similar content

Your part:

Backend setup (API proxy + fallback + caching)

Minimal adjustments in Flutter to connect to your backend

Optional: Help document or simplify backend maintenance

The project is urgent.
Please send me your portfolio, estimated price, and the fastest delivery time.
Thank you.
