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.
