Simulated patients platform

I'm a doctor building an AI-powered medical exam simulator called PACES Prep. Doctors practise patient consultations by speaking to an AI that plays the patient in real time, then receive structured feedback. I have a basic prototype and need the full product built from scratch. --- TECH STACK REQUIRED - Voice pipeline: LiveKit WebRTC + OpenAI Whisper (STT) + ElevenLabs (TTS) - LLM orchestration: LangChain + GPT-4 or Claude - RAG architecture with vector database (Pinecone / pgvector) - Frontend: Next.js | Backend: Django | DB: PostgreSQL - Payments: Stripe - Hosting: Vercel + AWS KEY FEATURES - Real-time voice consultation with AI patient - Clinical case library (30 cases at launch, admin-editable) - Post-session AI feedback and scoring - User accounts, dashboard, session history - Monthly subscription with free trial WHAT I NEED FROM YOU - A live demo of a comparable real-time voice AI project (required) - Proposed timeline and milestone-based cost breakdown - Confirmation that I own the GitHub repo from day one Please do not apply without a relevant portfolio example. Looking for someone who has built this type of app before, not someone learning on the job.
