From Mechanical Engineer to Cybersecurity Beginner - My Ongoing Career Shift

Four years ago, I was working as a mechanical engineer, focused on systems, machines, and processes that you could physically see and touch. It was a solid career—and one I’m still proud of—but something inside me felt restless. I was curious about tech, fascinated by the digital world, and increasingly drawn to the idea of working in cybersecurity.

Today, I work as an IAM (Identity and Access Management) Engineer. I won’t pretend I have it all figured out. Most days, I still feel like a beginner—and in many ways, I am. But I’ve come far enough to look back and say: I’m glad I took the leap.

Why I Took the Leap

Like a lot of career shifters, I didn’t start with a degree in Computer Science or any formal training in IT. What I had was curiosity and a desire to build something different for myself. I started learning online, asking questions, saying yes to small tasks at work, and leaning into the uncomfortable feeling of not knowing.

When I landed my first opportunity in IT, I kept going. I slowly found my way into Cybersecurity, specifically in IAM, where I help manage who gets access to what in an organization. It’s a mix of logic, security, and structure—and while I’m still growing into the role, I love where it's heading.

What This Blog Is About

I’m starting this blog not as an expert, but as a fellow learner. If you're thinking of switching careers, starting fresh, or just curious about tech—I’m writing this for you.

You’ll find posts about:

  • What it’s like to shift into tech from a different field

  • Tips for beginners learning cybersecurity and IAM

  • Study resources, small wins, and lessons from my journey

  • A bit of lifestyle too—especially fitness, which keeps me grounded

The Gym and the Journey

I’ve always enjoyed going to the gym. In fact, lifting weights played a huge role in shaping my mindset during the career shift. It taught me about consistency, delayed gratification, and showing up even when it’s hard. I don’t hit personal records every day—but I show up. The same goes for my tech journey.

You Don’t Have to Be an Expert to Start

This blog is about starting, not arriving. I’m not here to teach from a podium—I’m here to walk alongside those who are figuring it out, just like I am.

So if you’ve been hesitating to try something new, to learn a new skill, or to start over—consider this your sign. You don’t have to be an expert. You just have to start.

Let’s figure it out together.
