I’m building an AI-powered learning application that must run smoothly on both iOS and Android. I’m open to either Flutter or React Native on the front-end, and Python (FastAPI, Django) or Node.js (Express, NestJS) on the back-end—whatever you feel will deliver the fastest, most maintainable result. Core scope The app’s heartbeat is an adaptive “Learning with AI” experience: dynamic lesson delivery, personalised recommendations, and progress tracking generated by an AI engine you will design and integrate. A secure user system is required; I haven’t locked in whether that’s email-password, social logins, or biometrics, so I’ll look to you for the most practical approach that keeps onboarding friction-free. Key deliverables • Cross-platform mobile app with clean, responsive UI • REST or GraphQL API and database schema ready for cloud deployment • AI module that serves tailored content and analytics in real time • End-to-end documentation, test coverage, and a hand-over walkthrough Tech you might reach for includes Flutter, React Native, Firebase/Auth0, PostgreSQL/MongoDB, TensorFlow, PyTorch, OpenAI, or similar—use what best fits the architecture you propose. If you can take the idea from prototype to store-ready build, let’s talk timelines and milestones.
