Claude Code: The Complete Course

Build real projects with Claude Code, Cowork, Skills, AI Agents, MCP, n8n, GitHub, Vercel, Obsidian & Claude Design

Claude Code is not just another AI coding assistant.

It is a new way to work with your computer: with your files, your terminal, your codebase, your tools, your automations, and your projects.

In this course, we turn Claude Code from “interesting AI tool” into a practical AI work environment.

The course is built around 3 main layers:

1. Claude Code Foundations

Installation, setup, IDE workflows, terminal basics, project structure, CLAUDE md, the .claude folder, modes, permissions, slash commands, custom commands, and the core workflow of working with Claude Code in real projects.

2. Practical AI Projects

Instead of only learning features one by one, we build real systems: a personal AI assistant, an Obsidian LLM wiki, a website from idea to deployment, n8n automation workflows, self-improving AI with autoresearch, and agents with the Claude Agent SDK.

3. Advanced Agentic Workflows

We go deeper into context engineering, MCP, skills, plugins, CLIs, NotebookLM, RAG, Telegram control, cron jobs, loops, hooks, subagents, parallel agents, Context7, Git, GitHub, Vercel deployment, Claude Desktop, Computer Use, and security.

The goal is simple:

By the end of the course, Claude Code should not feel like a mysterious AI tool anymore.

It should feel like a practical system you can use to build, automate, research, test, deploy, and manage real projects.

The course includes 6 major hands-on projects:

1. Personal AI Assistant

Build a Claude Code assistant connected to Telegram, channels, plugins, skills, MCP tools, loops, scheduled tasks, and custom instructions. Similar in spirit to OpenClaw, but built around Claude Code.

2. Obsidian LLM Wiki

Create a second brain system with Obsidian and Claude Code for memory, documentation, RAG-style knowledge workflows, and personal knowledge management inspired by ideas from Andrej Karpathy.

3. Website Project with Claude Design

Build a website from the first idea to frontend design, testing, GitHub version control, Claude Design, and final deployment on Vercel.

4. n8n Automation System

Use Claude Code to create, improve, and manage n8n workflows for AI automation, workflow building, and practical automation systems.

5. Self-Improving AI with Autoresearch

Build an autoresearch workflow where Claude Code can research, improve, iterate, and work more autonomously on complex tasks.

6. AI Agents with Claude Agent SDK

Build agents in Python with Anthropic’s Claude Agent SDK, including a customer support agent and bonus workflows with Pydantic-based agents.

This is not a course about random prompting tricks.

It is a project-based Claude Code course for people who want to understand how AI coding tools, AI agents, automation, context engineering, MCP, RAG, GitHub, deployment, and real-world workflows fit together.

We start with the basics, including AI and API fundamentals for developers: LLMs, tokens, function calling, and the concepts behind modern AI tools.

Then we move step by step into Claude Code itself: installation, IDEs like VS Code, Cursor, and Google Antigravity, project structures, permissions, modes, context files, slash commands, custom prompts, skills, plugins, and CLI workflows.

After that, we build real systems.

You see how Claude Code can work with Telegram, Obsidian, n8n, NotebookLM, GitHub, Vercel, Claude Desktop, Computer Use, Context7, MCP servers, hooks, logs, scheduled tasks, subagents, and parallel agents.

The final section covers important security topics like tool poisoning, MCP rug pulls, permissions, AI agent vulnerabilities, and safe usage when giving AI access to files, tools, APIs, workflows, and your computer.

This course is for developers, AI builders, automation creators, n8n users, entrepreneurs, freelancers, students, content creators, and knowledge workers who want to use Claude Code in practical projects.

You do not need to be an expert developer to start.

The course begins with the basics and then moves into advanced Claude Code workflows, AI agents, automation, deployment, RAG, MCP, hooks, subagents, and real-world projects.

If you want to stop using AI only as a chatbot and start building useful AI systems with Claude Code, this course gives you the complete practical roadmap.

Who this course is for:

• Software Developers & Freelancers who want to revolutionize their workflow and become more productive
• Product Managers & Designers who want to build working prototypes and internal tools themselves instead of waiting for developer resources
• Career Changers & Beginners who, thanks to modern AI tools, can finally program complex full-stack apps without cramming syntax for years
• AI Enthusiasts & Hobbyists who want to go beyond simple chatbots and develop real, autonomous agents
• Indie Hackers & Solopreneurs who want to build and launch software
• Anyone who wants to master the modern tech stack to develop software faster than ever before.
