Have you ever had these concerns? I’ve learned React, but I don’t know what to actually build. I want to create a portfolio, but I can’t think of anything besides a Todo app. Map APIs or Public APIs seem difficult, so I haven’t even tried them. I’ve never deployed anything, so it always ends as a “local project.” The code is getting more complex, and I don’t know how to design the architecture. 🎯 Problems this course solves This course isn’t just about showing you how to display a map. ✔ How to connect Public APIs to a real service ✔ How to stably design Map SDKs within a React structure ✔ Marker optimization and reusable InfoWindow structures ✔ State management design using Context ✔ Practical application of Tailwind + SCSS ✔ GitHub organization and Vercel deployment I will teach you how to design with a real service structure, not just "implementing features." 💡 This is not a "just follow along" course Why we use useRef Why you shouldn't create new markers every time Why you need to separate state Why environment variables must be managed separately in production There is a reason for every choice. This course explains those "reasons." 🚀 After taking this course, you will: Complete one map-based portfolio project Gain experience integrating Public APIs Understand the structure of attaching external SDKs to React Gain experience in designing professional-grade project structures Have deployment experience And you’ll be able to say this in an interview: “I personally designed and deployed a map service based on Public APIs.” This one sentence makes a huge difference. 👩‍💻 Recommended for: Those who know basic React syntax but lack project experience Those who want to build a portfolio for employment Those who wanted to try a Map/Public API project Those who want to learn design patterns close to real-world practice 🔥 The Goal of this Course This course is not about “how to make a map,” but about learning the “mindset of designing a service.”
