FlutterFlow Auth & Dashboard Integration (Existing Backend)

PROJECT DESCRIPTION

I have an existing backend system already running and need a developer to complete the frontend integration and secure user data flow.

Current Stack (Already Built)

n8n (self-hosted) – production workflow running

Supabase (Postgres) – schema created and live

Email provider integration complete
AI processing workflow complete
Database tables populated via backend
The backend is functional and tested.
This project is for frontend integration and secure data binding only.

Scope of Work

1️ Supabase Authentication Setup in FlutterFlow
Configure Supabase Auth (email/password)
Connect authenticated user to database records
Ensure proper session handling
Implement redirect logic

2️ Database Binding
Bind authenticated user to:
profiles table
usage_counters table
receipts table
Queries must:
Filter by authenticated user UID
Respect Supabase RLS
Return only user-owned data

3️ Dashboard Page Build
Create a simple dashboard that displays:
User-specific email address (from profiles table)
Remaining weekly usage (from usage_counters)
List of user receipts (sorted by date)
Click receipt → open detail page

4️ Receipt Detail Page
Query receipt by ID
Display stored JSON fields
No redesign required, simple structured UI is fine

5️ Security Requirements
Ensure Supabase RLS policies are properly configured
No service-role key exposed client-side
Production-ready authentication handling

Requirements:
Strong experience with FlutterFlow
Strong Supabase knowledge (Auth + RLS)
Comfortable with n8n backend systems
Must understand filtering queries by auth.uid()
Clean, production-ready work (not prototype level)

Deliverables
Fully working Login → Dashboard → Detail flow
All data correctly filtered per user
Clean, documented configuration
No hardcoded test values

Important
The backend logic and concept are already complete.
This is strictly frontend auth + database integration.

Have you implemented Supabase Auth with FlutterFlow before?
If yes, describe the project briefly.

Explain how you would securely filter a Supabase table so users only see their own records.
Have you worked with Supabase RLS policies?
Give a short example of a policy you’ve written.
How would you prevent exposing the Supabase service-role key in a FlutterFlow app?
Are you comfortable working alongside an existing n8n backend?
