This course is not just simple clone coding or a basic tutorial. By implementing an LMS (Learning Management System) platform like Inflearn from start to finish at an MVP level, it provides an all-in-one solution that freelancers, solo developers, and early-stage startup members can immediately apply in real-world projects. We cover the entire tech stack used in actual production environments at once: Next.js, Flutter, Supabase, Firebase (FCM), AWS, Vercel, Xcode, Android Studio, ElevenLabs, and Toss Payments. You'll experience the complete process of simultaneously developing web and mobile apps, including social login, automatic multilingual dubbing, HLS streaming-based lecture playback, payment integration, and deployment to the App Store and Play Store. This course focuses on the important workflows, configurations, and deployment processes that matter in real-world development, rather than detailed line-by-line coding. Therefore, it's suitable for developers looking to become independent freelancers, teams that need to quickly validate MVPs at startups, and junior developers who want to experience the full scope of real-world development.
