# [Electron #1] Building a Timer App with Electron + React (With Zustand)

Using InstantID, IP-Adapter, and AnimateDiff v3, we create commercially deliverable 2D anime illustrations and animations while maintaining character consistency. We build a practical production pipeline that combines precise prompt control based on PonyXL with the Impact Pack detailer to automatically correct drawing defects, and completes high-quality loop videos with 4K ultra-high-definition upscaling and motion LoRAs.

This course covers the fundamentals of the Notion API and teaches you how to automate Notion by integrating AI (Claude) using Notion MCP. You'll learn to directly control blocks, pages, and databases by following the official API documentation, and ultimately complete a hands-on project that creates databases and automatically adds pages by analyzing text file content using only natural language commands (prompts).

Do you want to automate repetitive tasks with AI without using paid tools? I will share the practical know-how I gained from building systems myself using n8n and Llama. This is not a lecture where you simply learn "how to connect nodes." We will build actual workflows that you can use immediately, such as automatic Google Sheets organization, YouTube subtitle collection, AI fact-checking, and schedule management.

Are you feeling stuck with AI and payment integration, or production-level implementation? With know-how gained through countless trials and errors, I will help you complete a fully operational Voice AI SaaS. A simple demo is easy, but everyone gets stuck when trying to tie the entire cycle together—from upload and memo editing to credits, payments, and admin management. This course will guide you through that final stretch, putting a fully functioning voice-to-text product right into your hands.

Build a zero-cost pipeline by installing ComfyUI on Kaggle's free GPU, connecting via Pinggy tunneling, and linking it with n8n workflows to automatically iterate through Google Sheets prompts for bulk image generation, storage, and notifications. Through 10 chapters over 8 hours, you will practice everything from the ComfyUI node system to REST API conversion and n8n Loop/Webhook integration, reproducing the same results using provided JSON files. Even without programming experience, you will complete a practical automation factory that mass-produces SNS, advertisement, and thumbnail images unattended.

What if AI could directly open a browser and write shell scripts to resolve server issues? Through practical automation know-how implemented with OpenClaw across Windows and Linux, we guide you on the shortest path to completing your own powerful remote development environment without complex configurations.

Based on the experience of wondering how facial recognition works in offline environments on-site, this course will guide you through building the basic structure of a facial recognition-based access and attendance management system using React + Electron and Python's FastAPI-based DeepFace. Rather than focusing on perfection, we focus on understanding the operating principles and laying the foundation for you to expand into your own personal projects.

Starting with the question, "If I were on the Titanic, would I have survived?", this course completes a full-stack project where you develop an AI model to predict survival probabilities based on real data and deploy it as a web service. You will gain hands-on experience in the entire process of AI and web development, from deep learning modeling using PyTorch to building a backend server with FastAPI and implementing a user interface with Next.js.

In this course, we will practice step-by-step how to use React and FastAPI to implement social features such as real-time voting, comments, and likes, as well as how to monetize by integrating payment systems (Kakao Pay, Toss Pay, etc.).

The Next.js 15 App Router is a powerful architecture for building high-performance web services by perfectly controlling the boundary between server and client. This course clearly connects complex rendering mechanisms—from the operating principles of React Server Components (RSC) to the three major caching strategies (Static, Dynamic, and ISR)—through 12 practical missions. Through this, you will gain the ability to design file-system routing and nested layouts according to business requirements, completely breaking free from the anxiety of "vibe coding" where you copy code without understanding the principles. Ultimately, you will evolve into a Next.js architect who can instantly spot the blind spots in AI-generated code and proactively direct the optimal structure.

This is a project-oriented course where you will build a "ToDo List" app using React and TypeScript with a professional touch. Beyond simply learning syntax, you will gain practical experience in using TypeScript by completing a real-world service—from component structure design and state management to type application, feature implementation, local storage integration, and deployment.

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.”

The goal is to acquire basic knowledge of React Native for mobile app front-end development. This course is designed to enable non-experts to easily develop native mobile apps by utilizing languages/APIs with low entry barriers.
