Hi I can build your AI-powered English learning app for iOS and Android using Flutter, Python FastAPI/Django, PostgreSQL, REST APIs, and scalable cloud-ready architecture. The key technical challenge is combining CEFR assessment, speech evaluation, writing correction, and real-time AI tutoring into one accurate and smooth learning experience. My solution is to design a modular backend with separate services for assessment logic, AI prompts, speech recognition, pronunciation scoring, learning plans, and progress analytics. For the mobile app, I will create clean user flows for registration, profile management, tests, daily exercises, AI conversation practice, notifications, and performance tracking. I can integrate modern LLM APIs, speech-to-text, text-to-speech, push notifications, secure authentication, file/audio upload handling, and personalized recommendation logic. The CEFR evaluation can be supported through structured test scoring, AI-assisted analysis, and rule-based validation to keep results consistent. I will also build maintainable API documentation, clean source code, and deployment-ready backend configuration. This approach will give you a stable, extensible learning platform that can grow with more lessons, languages, subscriptions, and analytics features. Thanks, Hercules
