The Complete Guide to Claude Code: From Basics to Service Deployment

Even without knowing a single line of code, deploy the idea you came up with today as a working web service today. A hands-on course that takes you through planning, design, functionality, data, and deployment all at once with Google Antigravity.

How to Finish, Not Just How to Get Things Done. This course is for those who have tried having AI do things for them but feel overwhelmed about where to start with their own projects. You’ll learn a workflow where you define the intent first, leave implementation and verification to AI, and use the result yourself before making a judgment. You’ll complete a deployment together once using a feedme clone and once independently with your own idea, learning your own way of working.

Hundreds of saved materials, but zero materials opened again. Materials that are just piled up and never looked at. Are you perhaps doing the same? We're sharing a case study of someone who built their own OS to solve this problem.

I will teach you Vibe Coding systematically from the ground up, following the exact curriculum refined while teaching over 10,000 students by a former Tech Lead with 10 years of experience in New York and LA startups. Together, we will build my own service, 'Kagong Map,' from scratch, learning the entire real-world workflow—from research, development, and deployment to operation and automation by delegating tasks to AI agents. I promise you two things: first, you will grasp the big picture of how a service operates so you can judge the AI's output yourself; second, you will learn how to embed workflows and standards into the environment so the AI produces consistent results every time. When you make the judgments and the AI follows orders effectively, your ideas become real services.

AI is only as good as you are. Learn vibe coding properly in three steps: how to use AI → essential foundational knowledge → project development. For those who want to learn vibe coding the right way, we deliver the core concepts that remain unchanged regardless of which AI you use, broken down into bite-sized pieces.

AI is no longer a choice—it’s a matter of survival. Cut development time from 3 days to 30 minutes, delegate repetitive tasks to AI, and focus on solving more important problems. With AI-native development techniques you can apply immediately in real-world work—not just theory—we’ll show you a surefire way to be recognized at your company as a “developer who excels at AI.”

It is difficult to complete a classification service using only AI API calls. Based on practical experience, I guide you through everything from implementation to deployment.

We will show you how Java backend developers using IntelliJ can maximize their productivity with Claude Code. In particular, we help you perfectly resolve the vibe coding environment issues faced by those using Windows environments.

Based on hospital and plastic surgery website development projects that repeatedly appear in the actual outsourcing market, this course is designed to help you build a practical website and admin system that can actually win contracts, rather than just simple examples. This course doesn't just end with making a website. Using AI coding tools and Next.js, you will complete a hospital website mockup project and use it as a portfolio on actual outsourcing platforms to learn the entire process—from selecting projects, proposing, and bidding to writing quotes. The following will be implemented based on Next.js: - Hospital and plastic surgery website development - Building main pages and service detail pages - Building an Admin CMS - Blog content management - Consultation inquiry system - Attachment upload and inquiry response structure - Login and permission handling - Admin pages and RBAC structure - Multi-language support - SEO optimization - Sitemap, RSS, OG image, and favicon configuration - GA4 & GTM setup - Deployment, domain, and subdomain integration - Maintainable project structure Furthermore, it doesn't just explain development: - How the hospital outsourcing market works - Which hospital website projects you should choose - What customers actually consider important - Why hospital websites are constantly being renewed - How to create mockup projects that help win contracts - How to apply and bid on outsourcing platforms - What criteria to use when writing quotes - How to register and showcase your portfolio - What problems frequently occur during outsourcing - How to design for maintenance and additional development We share these types of realistic, practical experiences. The goal of this course is not to complete a simple CRUD example. It is to experience the entire flow of a practical project—creating a hospital website portfolio that can actually be used for outsourcing proposals, presenting a structure and quote that is convincing to customers, and considering delivery and maintenance. This is a practical full-course lecture for those who want to increase development speed using AI coding while simultaneously raising the quality of the output and the possibility of winning outsourcing contracts.

This is an introductory course for those using Claude Code for the first time. You won’t do the coding yourself—Claude writes both the code and the configuration files. Starting with creating a psychological test in the browser, you’ll build a household budget using card transaction records, create an escape room game, and make a travel itinerary that connects to external services like Google Calendar and Notion. Since you learn each feature as it becomes necessary, you’ll also understand why that feature is needed.

Simple tutorials alone make it difficult to apply in practice. I will clearly pass on my professional know-how, covering complex state management and multi-agent design methods.

Learn how to efficiently manage multiple AI coding agents, including Claude Code, Codex, and pi, from a single screen. Starting with tmux concepts, you’ll practice using Herdr’s sessions, panes, plugins, and CLI to build an agent workflow that keeps your work running even when your SSH connection is interrupted. Complete the essential development environment for the Agent era in just one day.

We explore how to create an AI judge by combining knowledge graphs, reasoning systems, and various agent frameworks such as CrewAI, LangChain, and AutoGen, which enable the implementation of LLM-based multi-agent technology.

With the arrival of the AI era, the skills required of developers are becoming increasingly complex. You might have thought, "I just need to be good at frontend," but when you try to create your own service or integrate AI features, you eventually hit a massive wall called the backend. However, as you try to start backend development, are you overwhelmed by how much there is to learn—from database design and authentication (Auth) to storage management and complex infrastructure setup? Now, you can lay down that heavy burden. In this course, we use Supabase, which solves all these backend functions at once. We will guide you through the fastest shortcut to becoming a full-stack developer who can "instantly" complete a backend without complex server knowledge and bring ideas to life immediately.

The “AI Team Members Do It All” online course is a hands-on program where you learn to use AI not simply as an automation tool, but as an “AI team member” that works alongside you in carrying out practical tasks. The course is structured around common real-world workflows, including market research, proposal writing, strategy report creation, brand content visualization, project promotion and operations, and post-project management. Participants assign various AI tools—such as ChatGPT, Perplexity, Copilot, Canva, Gamma, Miricanvas, and Vrew—to roles including planning partner, strategic research partner, design partner, and operations support partner, and use them to complete actual work deliverables. Across 30 sessions, you will learn step by step, from the fundamental mindset for working with AI to practical prompt writing, market research, proposal and report writing, brand content creation, and project operations. By following the course, you can develop the AI collaboration skills needed to work independently like an entire team.
