Your technology
in good hands.
Security, development and systems for companies that cannot afford failures. Over 20 years solving what others complicate.
Does any of this ring a bell?
These are the most common issues I see in companies without a trusted technical person.
A breach can sink you
60% of SMBs close within 6 months after a cyberattack. It's not paranoia, it's statistics.
Your tech grew without order
Patch upon patch. Nobody really knows how everything works together. One day it fails and nobody can fix it.
Firefighting all day long
Without someone you trust, every technical incident becomes a crisis that costs you time and money.
You don't know what you need
They sell you solutions you don't understand. You overpay for things you don't use. Nobody speaks plainly.
If you nodded to any of these, I can help you.

Bienvenido al Underground
Donde empezó todo. Phreaking, BBS, y las raíces de la cultura hacker.
Why they trust me
It's not just experience. It's public code, real projects and repeat clients.
Hi, I'm Antonio
I've been in technology for over 20 years. I started at 9 writing BASIC on an Amstrad CPC464, and in the 90s I discovered the world of phreaking and BBS. There I learned that systems always have hidden doors.
That curiosity to understand how things work from the inside led me to work in different companies touching systems, networks and cybersecurity, creating mobile apps, and now help companies protect what others would try to exploit.
What sets me apart is that I think like an attacker, but work as a defender. I speak plainly, get to the point, and when I say something can be done, it gets done.
I also co-host the VidaGeek podcast and write on the blog, where I share what I learn from the underground to today.
