Dipping into FastAPI (FastAPI + React.js + AWS LightSail)

In this course, you will build a system that directly parses DWG drawings in Unity and automatically converts them into actual 3D walls based on lines and polylines. After completing the DWG → 3D map automatic generation pipeline, you will also implement map editor functionality that allows you to freely place various objects on the generated space and save/load them in JSON/DB format. Finally, by integrating essential features used in real-world digital twins such as heatmaps, status displays, and real-time data reflection, you will complete a digital twin project from start to finish that can be immediately applied in industrial settings.

Let's begin developing with Copilot (copilot). With AI, even elementary school students can follow along!

A lecture that allows you to clearly understand the basic concepts of React by learning with illustrations.

This course is designed to teach React.js to web developers from the ground up—even if you have never written React code before. I guide students step by step, starting from the basics of JSX, components, props, state, and events, all the way to integrating API requests and building fully functional web applications. By following real-world projects like a Netflix Clone and an Admin Dashboard, you will not only understand React concepts but also learn how to solve real development problems efficiently. My approach ensures no student is left behind, providing clear examples, explanations, and practical applications of React in dynamic, responsive web interfaces.

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.
