Abel Alamillo

Hey! I’m Abel. I’m passionate about cybersecurity and lately, I’ve been diving into the cloud to see how security fits into it all.

Right now, I’m exploring AWS, Terraform, Python, and CI/CD, applying security-first thinking to everything I build. I love breaking things down, locking things down, and learning how it all works under the hood.

When I’m not deep in cloud configs or writing blog posts like this one, you’ll probably find me fine-tuning my portfolio—or climbing something way taller than I should be.

Interests

Outside of cloud security and building homelabs, I’m someone who genuinely enjoys spending time outdoors. Whether it's scaling a rock wall on a climbing trip, exploring new hiking trails, or just kicking back with friends in the sun, I find being outside incredibly refreshing and grounding. There’s something about fresh air and a bit of adventure that helps me recharge.

Of course, when the weather has other plans—or when I’m stuck inside due to being under the weather—I switch gears. I love diving into a good anime series, getting lost in fantasy movies, or hopping into a game with friends. I’m also a bit of a foodie at heart. I’m always on the lookout for new restaurants or hidden gems in the area, and I’ll never say no to trying something new on the menu.

Me Climbing Rocks.
