I’m building a mobile app whose heart is an AI-driven mental-health companion. The core experience is an always-available chat where users can speak freely and receive evidence-based guidance from an intelligent agent. Around that, I want to give them the practical next step of scheduling sessions with a licensed doctor or dietitian directly inside the same interface, so the hand-off from self-help to professional help feels seamless. The chatbot logic should feel natural, empathetic and safe. Think GPT-style conversational flow, sentiment detection, and an escalating protocol that offers doctor or dietitian bookings whenever the user’s language or progress suggests it would help. I’m open to which stack you prefer—React Native, Flutter, Kotlin/Swift, Firebase, Node, Python, LangChain, TensorFlow, or your own proven mix—as long as the app runs smoothly on iOS and Android and data privacy standards comparable to HIPAA are respected. Key screens I need: onboarding with mood baseline, AI chat with contextual suggestions, calendar view showing real-time doctor/dietitian availability, and a lightweight user dashboard for progress snapshots. Stripe or similar will handle payments; Twilio or a native module can send appointment reminders. I value clean architecture, readable code, and clear documentation that lets my internal team continue iterating after launch. If your background includes shipping mental-health, tele-medicine, or scheduling products, tell me about it—experience is the main thing I’ll use to choose a partner. Links to live apps or repos are even better. When you reply, briefly outline: • the tech stack you’d use • one past project that proves you can deliver a secure, conversational app at scale • your estimated timeline to a testable MVP Looking forward to collaborating on something that genuinely helps people feel better and get care faster.
