I’m Harold Briceño, IT systems engineer living in Santiago, Chile, originally from Venezuela.
I’ve spent 15+ years keeping companies’ technology running — from hands-on support through systems administration to where I work today: Microsoft 365, Entra ID, and Azure administration at enterprise scale, with identity, security, and cloud governance as my home turf.
Somewhere along the way I noticed the pattern behind every incident I ever resolved: things break where nobody is watching. The dormant account of an ex-employee. The share that was opened “just for now.” The MFA rollout that covered everyone except the three accounts that mattered. So my work turned into building the watchers: automation with PowerShell, Microsoft Graph, and AI that checks the boring-but-critical things every day, so they never become an emergency.
What I’m doing now
- Administering Microsoft cloud environments (M365, Entra ID, Azure) for an enterprise in Santiago.
- Studying for the SC-300 (Microsoft Identity and Access Administrator) certification.
- Building El Guardián — an automated governance system for small businesses’ Microsoft clouds: identity hygiene, security posture, and cost control, watched daily by software and judged monthly by me. If your company runs on Microsoft 365 and nobody owns its security, that’s exactly the gap I cover (in Spanish — but I work in both languages).
- Writing here: practical notes on identity, PowerShell + Graph automation, AI-assisted IT engineering, and honest war stories from the trenches. Everything I publish is something I actually ran.
Why this site exists
My work, scripts, and lessons used to be scattered — or worse, lived only in my head. This site is the permanent home where all of it accumulates: something I own, at my own name, built to still be useful years from now.
