Joao Silva AKA Ciberjohn

Cybersecurity and AI, from someone who has to make them work on real systems.

I'm João Silva (ciberjohn). Senior infrastructure manager by trade, so the videos here come from things I had to fix rather than things I read about: making an AI agent remember across sessions, replacing subscription software with self-hosted alternatives, Linux admin work, and reading security news past the headline.

Responsible AI gets its own thread as well: a six part walk through the EU AI Act, and the questions most teams skip right before they ship.

Every tool I show has been running on my own hardware, and the skills I write get published open source on GitHub. No sponsors, no demo-ware.

I co-host the CyberMonday security segment on Coffee & Bytes with Rui Costa: coffeenbytes.com
