About

Field discipline, now applied to the cloud

I am a Systems & Networks Administrator based in Arlon, Belgium, near the Luxembourg border. Four years of hands on ISP and network engineering work taught me how real infrastructure actually behaves under pressure, not just how it is supposed to work on paper. I am now applying that same field discipline to Microsoft hybrid cloud and cybersecurity, working systematically toward architect level capability.

I also genuinely enjoy teaching. At Screamer Telecoms I trained engineers, call-centre agents and field technicians, and that habit of explaining things clearly carries directly into how I document this project.

Takeaway Every milestone documented as it happens, in public.

Principles

How I work

Honest by default

Nothing on this site claims a skill I do not have yet. Progress is labelled in progress or planned until it is done.

Documented as it happens

Decisions, runbooks and weekly notes are published as I work, not polished afterwards.

Explained clearly

Three years of training engineers shaped how I write: plain language, with the reason behind every step.
