Course Description
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.

I like the pace and the details - it is absolutely doable to follow as a non-programmer. The practical application is less relevant for my case, but hopefully the next projects can be more applicable.

Der Kurs ist sehr gut. Danke für den Tipp mit dem Schneller-abspielen (1.25x ist super für mich). Mir fehlt z.b. die Datei claude_code_presentation_short.html die Du vorstellst, es wäre besser sie bei den Materialien dabei zu haben, z.B. via github
By Ahmad Alizadeh on 8/7/2026
Provided a good overview of AI with acceptable examples.
By Anthony Robert Young on 7/18/2026
Just a great, detailed introduction into Claude code, with practical builds and deeper dives aong the way. Arnie has a clear style of teaching and explains decision making well. Highy recommend this course.
By Wai Siu Lai on 7/4/2026
This course takes a lot longer because he basically tells you about this feature and tells you to go try it. There was some interesting stuff but he only shows us toy examples. Basically this is more of a feature overview not a "complete course"
By Kusumajaya Na on 6/9/2026
Really fun experience for doing this course. Not only am I able to build my first personal webpage, but also I learned a lot on how to use claude ai in general
By OS Legend on 5/27/2026
Arnie’s courses are always the best. I’m super happy with everything he’s delivered to me, not just in this course but in the other courses he’s developed. Great work, Arnie! Keep it up!
By Miriam Wojcik on 5/13/2026
It would be useful if downloadable resource files were provided for fake examples. Nobody has time to write up made up context for a fake business. Also too light on technical definitions.
By Tony Grant on 4/29/2026
The instructor simplifies and solidifies the relationship Between Claude Code and its Harness, making it easier to underatand the process going forward.
By Sakeriye Hujale on 4/29/2026
The instructor breaks everything down in a way that's incredibly easy to follow — no fluff, no unnecessary padding, just practical, hands-on content that gets you results fast. I especially appreciated how each lecture built on the last, so nothing felt overwhelming.
