What I'm looking for

I seek a hands-on cybersecurity role where I can lead SOC operations, mentor teams, advance threat-hunting capabilities, and contribute to incident response programs within a collaborative, security-focused organization.

I am a SOC lead with practical experience managing 24/7 protection, threat hunting, incident response, and network monitoring across multiple SIEMs and XDR platforms. I progressed from hands-on technical roles in computer repair and support to system and network administration, and now lead SOC teams with expertise in blue and red team operations.

I have delivered technical support for international regions, administered networks and firewalls (Fortinet, Check Point), and provided cybersecurity training to law enforcement and MSME programs. I bring strong communication skills, proficiency in English (C1), and a history of applied digital skills including SIEM/XDR operations, incident handling, and technical leadership.
