Welcome!

Welcome to my Wiki! Here you can find who I am.

TL;DR My career path has been the following:

Hardware repair/installation: I used to drive the van and go to customers to do these kinds of tasks: repairing, installing, and configuring PCs, racks, switches, routers, firewalls…
IT Technical Specialist (NOC): support for 100+ different customers with diverse infrastructures and autonomous on-site activities.
System Administrator (SOC): Malware and Mail Threat Analysis, secure domain management, networking and endpoint hardening.
Cloud Engineer (Open-Source): Linux, Git, Ansible, AWX, Terraform/OpenTofu, MAAS, BareOS, KVM, QEMU, LXD/LXC, Docker, Kubernetes, Ceph, OpenStack, Kafka, Observability (ELK Stack, Prometheus, Telegraf, Victoria Metrics, Grafana…), scripting (Bash, Python, PowerShell), networking (including BGP), and much more…

In this Wiki, I collect everything that is essential to operate in the roles mentioned above in a professional and methodical way.

What sets these notes apart from simply asking an AI for advice is that here you’ll find:

real-world experience from someone who has worked in large and international environments, on production systems with on-call rotations
focused yet detailed content, presented in a concentrated and tightly consistent way
useful integrations: links to theory, tools, and software to simplify work and improve its quality

The notes are truly interconnected: each one is a node in a graph, so they contain only what is strictly necessary.

You can physically see all the knowledge connections required for a topic, and navigate through them without ever encountering repetitions.

The full set of connections around a given topic gives you a realistic view of its depth and what you need to fully understand it.
