Description

Cybersecurity is not just about hacking systems: it's the art of understanding them, step by step.

As an Associate and Cybersecurity Engineer at ITNET Technologies, I bridge the gap between robust infrastructure and offensive security. With expertise in System Administration and a degree from ESEO, I now operate at the heart of DevSecOps.

My strength lies in mastering the complete system lifecycle: I know how to build it, administer it at an expert level, and defend it by adopting an attacker's mindset.

🛠 What I do:

Strategic Vision: As an associate, I align technical security imperatives with the company's growth objectives.

DevSecOps & SysAdmin: Automation of security in CI/CD pipelines and management of complex system architectures.

Offensive Security: Mastery of the pentest lifecycle, from reconnaissance to exploitation.

I document my technical journey and share my discoveries in my LinkedIn series: "Journal of an Ethical Hacker."

🎯 My goal: To leverage my expertise in systems and automation to become a recognized expert in Pentesting and Cyber Engineering, to help organizations build resilient and proactive security postures.

👉 Always open to sharing knowledge, exchanging ideas, or collaborating on complex security and infrastructure projects.
