Experienced Cloud Architect with over 15 years of expertise in Cloud Architecture and Operations, CyberSecurity, and AI-driven systems.

I consistently drive innovation and efficiency across large-scale cloud infrastructures to enhance reliability, scalability, and performance for global enterprises. With a cybersecurity focus dating back to my university years and thesis work, I have continuously applied security-minded thinking across software, infrastructure, and cloud initiatives.

Born in 1988 and based in Cyprus, I specialize in aligning technology solutions with business goals for growth and resilience.
