IT made simple. A classroom with a terminal, not a slide deck.
I'm Raffael, software architect and IT trainer. Here you get the courses I run for companies across Europe, as self-paced workbooks: containers and OpenShift, Java and Spring Boot, Kafka, Databricks and Spark, and practical AI for engineers.
Every course follows one sample project from the first command to something you can show. Every module has the theory you actually need, every command with its output, and labs with full solutions. The material is an offline HTML workbook: download it once, keep it forever.
How it works in here: post your broken command and get a real answer, not a link to the docs. Show what you built. Vote on which course gets built next.
One rule: you understand something when you can explain the error message, not when the slide says so.
