OT Security Consultant | Systematic Skill Development | 2,000+ Students

Three years ago, I started learning cybersecurity from zero—just curiosity and a systematic approach to mastering complex skills quickly.

That system worked. Within 18 months, I became Lead OT Cyber Security Engineer at a Fortune 500 company, securing critical infrastructure. Today, I consult at a top-tier firm protecting the UK’s most critical industrial systems.

But here’s what I discovered: The skill that changed my career wasn’t just technical knowledge—it was learning how to systematically master high-value skills that companies desperately need.

Most people struggle not from lack of ability, but from lack of system. They spend years in trial-and-error when they could follow a proven path to expertise.

That realisation led me to teaching. Over 2,000 students across 100+ countries now use the same systematic approach that took me from complete beginner to securing critical national infrastructure in under three years.

Background

I started in cyber security as an apprentice at 17. Within two years, I was Lead OT Cyber Security Engineer responsible for securing a top-tier COMAH critical national infrastructure site—one of the UK’s most dangerous chemical sites where security decisions have safety implications.

After leading OT security at a Fortune 500 agricultural technology company, I moved into consulting on critical infrastructure across energy, utilities, and manufacturing sectors.

Professional highlights include leading £400k+ infrastructure security projects, designing systems that reduced attack surface by 99.5%, and creating OT security frameworks now used across multiple countries.

Then I started teaching—sharing the systematic approach to skill mastery that made this rapid progression possible.

My Mission

Help ambitious professionals systematically master valuable skills without spending years figuring it out alone.

This site shares what I’ve learned: technical expertise, systematic learning frameworks, and career acceleration strategies—all from real-world application.
