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 (no-code platform)

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

* Fixed scope only

* No feature expansion without approval

* MVP first, improvements later

OPTIONAL PAYMENT MODEL

Fixed price preferred:

* 300–900 EUR depending on experience

Milestones:

* 50% start

* 50% after delivery

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