FlutterFlow Developer Needed for AI-Driven Agriculture App (Supabase + OpenAI Integration)
Budget: €5,000 – €10,000 EUR
✅ Project Overview:
We need an MVP mobile/web application that helps farmers generate complete crop technology plans using AI.
The app must be simple, fast, and functional, with a clean UX optimized for non-technical users (farmers).
The core feature of the MVP is:
User inputs basic farm data → app sends it to ChatGPT API → app displays a complete crop technology plan (PDF export included).
✅ Technology Requirements:
Preferred tech stack:
FlutterFlow (frontend)
Supabase (authentication + database + storage)
OpenAI API (GPT-5 or GPT-4.1) for AI generation
PDF export (frontend or server-side)
Alternative acceptable stack:
Bubble + OpenAI + Firebase (only if developer has strong Bubble expertise).
✅ Core Features (MVP Scope):
✅ 1. Authentication
Login with phone number
OTP verification
User profile stored in Supabase
✅ 2. Crop Selection Screen
User chooses crop from list (initial MVP scope):
Wheat
Corn
Sunflower
Rapeseed
Dynamic list (Supabase-based) is preferred.
✅ 3. Farm Data Input
Simple form with:
Farm surface (ha)
Soil type (argilos / lutos / nisipos / luto-nisipos)
County (dropdown with all counties of Romania)
✅ 4. Input Inventory (checkboxes)
User selects agro-inputs they already have.
Fertilizers (checkbox list):
Urea
NPK
DAP
Ammonium Nitrate
Ammonium Sulfate
Herbicides (checkbox list):
5–10 common options per crop.
Fungicides / Insecticides (checkbox list)
5–10 common options per crop.
Farm equipment:
Disc
Combinator
Seeder
Sprayer
(This list must be stored in Supabase so it can be edited later.)
✅ 5. AI Integration
When user taps Generate Technology, the app:
Builds a structured prompt using user inputs
Sends it to OpenAI API
Receives structured text with full crop technology:
Soil work
Sowing
Fertilization (3 phases)
Herbicide plan
Fungicide/insecticide plan
Monitoring
Harvesting
Estimated costs
Displays results in a clean, collapsible UI.
Developer receives the Core Prompt from us.
✅ 6. Results Page
Must include:
Generated technology (section-based, collapsible)
Button Download PDF
Button Share via WhatsApp
Button Save to My Technologies
✅ 7. History Page
User can see all previously generated technologies:
Date
Crop name
Button to open
Button to download PDF again
✅ 8. Admin Panel (simple)
Built using Supabase Dashboard:
Edit list of crops
Edit list of fertilizers
Edit list of herbicides/fungicides
Edit list of equipment
No need for dedicated UI in MVP.
✅ Design Requirements:
Clean, simple UI.
Preferably Google Material or basic FlutterFlow UI kit.
Target user = farmers → must be:
large buttons
clean spacing
strong contrast
minimal screens
Developer must provide basic UI/UX inside FlutterFlow.
✅ Deliverables:
Full FlutterFlow project
Supabase schema (auth + tables)
All API calls connected
Testing of 10 full flows end-to-end
Deployment to web (MVP)
Optional: deployment to Android/iOS (if developer can do this)
✅ Timeline:
4–6 weeks for full MVP.
✅ Budget:
5.000 – 7.000 EUR (fixed price preferred)
Also open to hourly if developer has verifiable FlutterFlow experience.
✅ What to include in your proposal:
Examples of FlutterFlow projects
Experience with OpenAI API
Example of an app integrating API → PDF export
Estimated delivery time
Breakdown of milestones
Tech stack confirmation
