I am looking for a developer to build a simple MVP web application.
The application is an AI-powered English learning trainer.
The goal is NOT design or scaling, but a working functional prototype.
⸻
CORE FUNCTIONAL REQUIREMENTS (SCOPE)
1. User System
* User registration
* Login / logout functionality
⸻
2. User Profile
User must be able to enter and store:
* Name
* English level (A1–B2)
* Learning goal (Travel / Business / Daily Life)
This profile must be used in AI responses.
⸻
3. Main Training Screen
A simple input/chat interface where the user enters a sentence (English or German).
The system sends the input to OpenAI API and returns:
1. Correct English (grammar correction)
2. Natural English (native expression)
3. Alternative expressions (2–3 variants)
⸻
4. Scenario Generator
A button: “New Scenario”
The AI generates real-life situations based on the user profile, for example:
* Restaurant
* Airport
* Hotel check-in
* Shopping
* Small talk
User responds to the scenario and receives the same correction output.
⸻
5. AI Integration
OpenAI API must be integrated.
The prompt logic must:
* correct user input
* improve natural English
* generate next scenario
* use user profile context
⸻
TECH STACK (FIXED)

Bubble
* OpenAI API
OpenAI
* Bubble internal database (or Firebase if needed)
⸻
NOT INCLUDED (IMPORTANT)
* No App Store / Google Play deployment
* No voice features
* No payment system
* No animations or advanced UI design
* No scaling architecture
* No gamification
Only MVP functionality.
⸻
DELIVERY CRITERIA (VERY IMPORTANT)
The project is complete when:
* User can register and login
* User can input text
* AI returns:
* Correct English
* Natural English
* Alternative expressions
* Scenario generator works
* User profile is used in AI responses
If all above works → project is accepted.
⸻
WORKING STYLE

* MVP first, improvements later
⸻
OPTIONAL PAYMENT MODEL
Fixed price preferred:
* 300–900 EUR depending on experience
Milestones:

Please only apply if you have experience with Bubble and OpenAI API integration.
