CISO | Technology Director | Cybersecurity & Network Architect | ISO 27001 LA | Major (OF-3)
About
I turn complex tech challenges into simple, scalable solutions. With over 15 years in the IT industry and graduating top of my class in my MSc, I operate at the intersection of technical expertise, strategic vision, and decisive leadership. As a Major (OF-3) in the Hellenic Armed Forces, I’ve led large-scale IT operations and cyber defense initiatives in high-pressure environments. I currently serve at the Hellenic National Defence General Staff (HNDGS), contributing to national-level digital defense strategy.
Throughout my career, I’ve worn many hats:
- IT Director & Strategic Planner
- Senior System Administrator (Windows/Linux/Virtualization)
- Cybersecurity Expert
- Network Architect
- DevOps Engineer
Recent highlights include:
- Designed and deployed a full-scale SIEM solution (400+ endpoints), slashing the cost by ~70%
- Led network architecture overhauls across 12 sites
- Drove ~50% IT cost optimization across multiple military departments
I don’t list every technology I’ve worked with — I’m quick to master what’s needed and focus on delivering results. Thus, I translate military-grade precision into strategies that boost productivity and growth for businesses.
