Hola amigos, I’m looking for a developer who can help me complete the MVP of a language-learning web app already started on Replit and connected to Supabase. There is significant ongoing work available, so I’m looking for someone interested in a long-term collaboration as we scale the app. You can view the current prototype here: 👉 https://language-app-1-noah436.replit.app/home Students can currently log in via Supabase and practice with the conversation partner, but the experience needs substantial improvement. 🔧 Phase 1 MVP — What We Need Right Now Your first responsibility will be to optimize and stabilize Level 1 Conversation Partner, ensuring students can actually learn and practice with the AI in a structured, level-appropriate way. Phase 1 includes: Improving Level 1 conversation flow so the AI guides students based on our curriculum Connecting each student to their custom GPT conversation partner (GPTs already built in ChatGPT) If there's a better architecture than Custom GPTs, I'm open to recommendations Embedding the chat partner inside the app with a clean, mobile-friendly interface No separate ChatGPT login required Using the OpenAI API to connect securely to our custom GPT logic Additionally, the app should display simple placeholders/options for coming features: Practice with digital flashcards Learn with video lessons AI homework feedback Practice with real people Pay for and schedule classes These do not need to be functional yet — just clean placeholders to reflect the roadmap. This is the MVP we need immediately so we can begin structured student testing. 🛠️ Current Tech Stack Replit (frontend + backend) Supabase (auth + database) OpenAI API (I will help support API integration) 🔮 Future Features (Not part of this contract) We will add these after MVP validation: Embedded video lessons Flashcard practice via Quizlet Daily practice reminders Student progress tracking Premium subscription upgrade Additional AI conversation levels Teacher dashboard AI homework correction Live practice opportunities Class scheduling + checkout Right now the priority is a functional interactive AI conversation partner. 📩 To Apply, Please Include: Examples of apps or prototypes you’ve built using OpenAI, GPT, or similar APIs Confirmation that OpenAI API → Replit → Supabase is workable for you Your hourly rate within the $8–$12 range Your timeline for Phase 1 delivery Any suggestions on tech stack or architecture as the app scales Whether you're available for long-term work beyond MVP 🙌 About Us The Language School’s mission is to unite Spanish and English speakers through conversational exchange.
