About AAAGGGH And What Drives It

AAAGGGH.Com is owned by Liam McCabe and here is a little about me.

I’ve spent my life building, breaking, and rebuilding the digital world.

I’ve walked a long and winding path, from commercial web developer to cybersecurity lecturer to patented inventor all with one mission: to help people see the invisible threats that surround us online and to arm them with the knowledge to fight back.

A Relentless Pursuit of Knowledge

My academic foundation is built on a passion for both education and technology

Degree in Training & Education (2005) where I learned how people truly learn.

Postgraduate Diploma in Learning & Teaching (2015) refining the craft of turning complex concepts into powerful, accessible knowledge.

Higher Diploma in Science in Computing (2016) diving deep into the systems that run our digital lives.

Master’s in Cybersecurity (2019) specialising in the very core of digital defence in a world full of threats.

What I Teach, And Why It Matters

Today, I lecture across an ever-evolving list of topics designed to reflect what the world needs most

Secure Application Development

Secure Web Development

AI & Machine Learning for Cybersecurity

Mobile App Development

Database Design & Security

Business Resilience & Incident Management

Cybersecurity Fundamentals


But my teaching is never just academic. Every course I deliver is rooted in real-world relevance because threats don’t exist in textbooks. They exist in phones, inboxes, apps, routers, and every place we tap without thinking.

More Than Theory I Build Solutions

Before the classroom, I lived in code. Years of commercial web development gave me a front-row seat to how security is often an afterthought and how dangerous that can be. It also gave me the tools to do something about it.

In 2023, I was awarded US Patent No. US11871229B2, for a system I invented to eliminate Wi-Fi passwords using blockchain-based consensus. It’s a method that connects users to wireless networks without traditional usernames or passwords — completely sidestepping one of the most common attack vectors in existence.

This isn’t just innovation. It’s a war on guessable credentials. It’s a way forward.

Why I Created These Guides

Every day, I see people walking blind through a world full of digital traps. Parents. Business owners. Students. Friends. Good people who don’t realise that every notification, every click, every connection is another chance to be profiled, scammed, or breached.

I created these guides to change that. To open eyes. To stun people with truths they never considered and to give them the tools to do something about it.

My approach is direct, sometimes shocking, but always rooted in real-life examples. I don’t do jargon. I do impact.

Because digital safety shouldn't be a mystery. It should be a mindset.

Let’s build that mindset one guide at a time.
