API and backend integration for Flutter apps
An app is only as useful as the systems behind it. I connect Flutter apps to your backend and agree the details with your backend team first.
Fixed price, quoted after a 15-minute call.

Frequently asked questions
Do you build the backend?
I set up Firebase or Supabase as a back end, and I integrate with Laravel and other REST APIs built by your team. If you need a custom backend built, tell me on the call and I will say honestly whether I am the right person.
What do you need from my backend team?
API documentation or access to the endpoints, and a contact to agree the contract, payloads and error responses.
How do you handle errors and slow connections?
Error handling is agreed as part of the API contract, and apps can store data locally and retry when a request fails.
Which should I choose, Firebase or Supabase?
It depends on your data and your team. I explain the trade-offs on the 15-minute call before the scope is fixed.
Can the app have different user roles?
Yes. ReadyMix Deals serves client and factory roles from one app on a Laravel API.
