About Me

As a dedicated IT professional, I bring hands-on experience in system administration, virtualization (VMware, Hyper-V), and cloud infrastructure, particularly with AWS foundations. My current role as a System Engineer allows me to provide 24/7 operational support for critical VoIP and call center platforms like Vicidial and 3CX, while also managing and optimizing both Windows and Linux servers.

I am keenly expanding my expertise into offensive security, focusing on penetration testing and web application security. This includes in-depth study of OWASP Top 10 vulnerabilities, common attack vectors such as XSS and SQLi, and practical application of tools like Burp Suite. My commitment to continuous learning is demonstrated through ongoing certifications like CompTIA Security+ and active participation in TryHackMe labs. I am driven to leverage these evolving skills to contribute to robust security practices and innovative solutions.
