Build MVP Social Question App

Title: Build MVP Social Question App (Web + Mobile Responsive) with AI Reports Description: I am looking for an experienced full-stack developer to build an MVP for a social psychology entertainment platform called Rogatus. The concept is simple: Users send thought-provoking questions to friends, friends answer, and the platform generates a humorous and insightful report based on the responses. This is an MVP intended to validate product-market fit, so I am looking for a lean, practical implementation rather than an enterprise-grade solution. Core Features: User registration and login Profile creation Three onboarding identity questions Question categories Question selection Ability to create custom questions Send questions to friends via link, email, or SMS Response collection Group question rooms AI-generated reports AI-generated follow-up ("rabbit-hole") questions Basic admin panel for managing questions and categories Example User Flow: User creates account User answers 3 onboarding questions User selects a category User selects a question User sends question to friends Friends answer System generates report System suggests follow-up question Technical Preferences: Open to recommendations, but currently considering: React / Next.js Firebase or Supabase OpenAI API integration Mobile responsive design Important: Simplicity is critical Focus on functionality over perfect design Source code ownership must transfer to me Please recommend the fastest and most cost-effective architecture When Responding Please Include: Technology stack recommendation Similar projects you have built Estimated timeline Fixed-price quote Whether you would build this as: WordPress React/Firebase No-code / low-code Other Please also tell me what features you would remove or simplify to get the MVP live as quickly as possible. Budget: Open to proposals. Preference for a lean MVP that can be launched quickly and iterated over time.
