What I'm looking for

I seek a hands-on cybersecurity or systems role where I can perform vulnerability testing, incident detection, and systems hardening within a collaborative team.

I am a cybersecurity-focused IT technician with hands-on experience in penetration testing, systems administration, and incident detection. I have trained in ethical hacking techniques, vulnerability analysis, and post-exploit procedures, and I apply those skills to strengthen defenses.

My practical experience includes installing and configuring ADDS, DHCP, DNS, WDS, Bind9, postfix, VoIP and SSH services, creating and managing certificate authorities, and deploying Wazuh for monitoring and incident analysis.

I have completed roles and internships in IT support, database administration, and technical assistance, and have implemented projects such as a Java Swing game and virtual machine setups. I also have experience executing practical attack techniques like MITM, phishing, brute force and network scanning in controlled scenarios.

I work well under pressure, communicate effectively with clients, and focus on clear reporting and remediation. I am driven to join teams where I can apply technical depth in cybersecurity operations and continuous improvement of system security.
