I was born and raised in Athens, Greece, and for the past eleven years I've been living in Bratislava, Slovakia. My career began as a network engineer at AT&T, where I spent three years building my technical foundation. I then moved into cybersecurity, joining EPICOR as a cybersecurity analyst for another three years, gaining hands-on experience defending enterprise environments.
For the last four years, I've been with Takeda, where I lead a global, 24x7 team of cybersecurity analysts. Together, we respond to cyber threats that impact both our IT and OT environments, protecting critical systems and data around the clock.
I'm passionate about incident response and continuous learning.
