D.ANGELO — IT Infrastructure, Security & Governance
status: online — 20 years in production

IT infrastructure and security, explained by someone who ran it — not just read about it.

Analyst, Engineer, and Infrastructure Coordinator. This is where I break down tools, compare architectures, and share real decisions on governance and security for people who build and keep IT operations running.

// five pillars, one operator behind them

background

Twenty years between the server room, the help desk, and the boardroom

This site’s perspective comes from having sat in all three chairs: the one who executes, the one who designs, and the one who’s accountable for the outcome.

Phase 1
Infrastructure Analyst
The operational base: support, networking, servers, and day-to-day maintenance — where you learn how systems actually fail in practice.
Phase 2
Infrastructure Engineer
Design and architecture: virtualization, cloud, hardening, and building solutions meant to scale and withstand incidents.
Phase 3
Infrastructure Coordinator
Governance, compliance, and managing people and vendors — translating technical decisions into risk, cost, and business outcomes.
focus areas

Five fronts, one operator behind all of them

The content on this site grows out of these five pillars — each one grounded in field experience, not just research.

approach

Written by someone who’s been paged at 3am over an incident

Most technical content online is written by people who have never actually operated what they describe. Here it works the other way: every tool, architecture, or process recommendation gets filtered through “would I actually use this in production?” before it becomes an article.

That includes being upfront about limitations — no tool or solution fits every scenario, and saying so is part of the job.
