Three weeks.
Three systems you
actually build.

Each series runs Monday to Friday — a deck, a hands-on lab, an interactive playground, flash cards and a quiz. Not a tour of the vocabulary: every week ends with something wired, broken on purpose, and fixed.

Series 01 · n8n
Agentic automation: a team of agents inside n8n

One manager agent, two specialists on its Tool port, and a report that writes and sends itself. Twelve nodes, and the row of ports underneath an AI Agent node where most n8n builds go wrong.

Series 02 · LangChain
Stop scripting it. Let it decide.

Building intelligent agents with LangChain — one question, three tool calls, and a model that chose how many times to go round, in about twenty lines of Python.

Series 03 · RAG
Your demo works. Your handbook doesn't.

RAG engineering end to end — chunking, retrieval design, hybrid search, reranking and evaluation. You already know what RAG is; this is why yours returns the wrong paragraph, and the five stages that fix it.

DeckLabPlayground Flash cardsQuiz

The three stand alone — start with whichever problem you have this week. If you're picking cold, LangChain teaches the agent loop in plain Python, n8n shows the same idea as wiring you can see, and RAG is what you reach for once the agent needs to know something your model was never trained on.
