From a Sinclair ZX81 to complex infrastructure migrations.

The work behind the articles

I’m Zahid Rafiq, an independent infrastructure consultant. My work spans Active Directory, Windows Server, Exchange and infrastructure migrations, including discovery, design, testing plans and technical documentation.

I have worked across support, engineering, consulting and management roles for IT organisations, managed service providers and customers worldwide. Along the way, PowerShell has become an important part of how I investigate systems and automate repeatable tasks.

Why I started this blog

Like many administrators, I have spent hours looking for an answer only to find an incomplete explanation. A command might be present, but the prerequisites, limitations or final checks are missing.

This blog is a place to share technical instructions and practical context. My aim is to help readers understand what they are changing, why it matters and how to check the outcome.

Where it all began

My interest in computing began in the 1980s with a Sinclair ZX81. Its 1 KB of RAM and limited display were enough to spark a fascination with programming and how computers worked.

I later moved to a Commodore 64 and an Amiga, explored programming and reverse engineering, and wrote for Amiga User International. The arrival of Windows 95 prompted a move to a Pentium 90 PC, followed by my first desktop-support role in the late 1990s.

The equipment has changed considerably. The curiosity that started with that ZX81 is still there.
