AI & Automation Engineer Sistemes que funcionen sols

Treballo a IT en una empresa de logística. A casa mantinc un homelab amb agents d’IA i automatitzacions que faig servir cada dia, i documento com els construeixo.

Quadern El darrer que he escrit

  1. I talk to my homelab from my Apple Watch (and it is not allowed to do anything)

    A Siri Shortcut, a Raspberry Pi, n8n and an agent: how I ask my homelab questions from my wrist for 0.2 cents, why the voice path is read-only, and what an independent security review found before I open-sourced it.

  2. An ops agent for my homelab: MCP, LangGraph and a gateway that keeps the bill honest

    How I made my self-monitoring homelab answerable: a read-only MCP server, a LangGraph diagnosis agent that cannot execute anything, models routed by evaluation, and the numbers (and cost mistakes) behind it.

  3. A homelab that runs itself: monitoring, backups and updates on a Raspberry Pi

    How a Raspberry Pi and a desktop became a self-monitoring homelab: VPN-only access, a daily doctor script, 3-2-1 backups with a tested restore, and controlled updates, plus the incidents that taught me the most.
