We are launching Bandfy a mobile-first AI-powered music-learning web app (PWA) designed for iOS Safari and Android Chrome. We need a skilled front-end developer to build the entire PWA using React, Tailwind, WebAudio and Recharts, integrate it with our backend and AI APIs, and implement 27 screens (recording/analysis layers, premium-analysis, onboarding, store & paywall, settings, etc.). The scope covers song upload, recording, playback, membership tiers (Free / Standard / Pro) with trial logic, and seamless integration with AI-powered analysis, feedback and scoring. Provided materials include complete UI/UX designs, API documentation, data structures, membership logic and media assets. Your tasks will include PWA optimization, mobile-browser compatibility, basic QA and API integration testing.
