Cloud Security Architecture · Azure & Identity Security · Security Automation · AI Engineering · Product Development
I'm a cybersecurity engineer, technical founder, and hands-on builder based in Thessaloniki, Greece.
My work spans enterprise cloud security, identity and access management, security architecture, automation, and applied research. I currently work as a Senior Cloud Security Engineering Lead at Pfizer and lead the technical development of Sinartisis, a venture building security-focused software for the Microsoft cloud ecosystem.
Previously, I worked with CENSUS, GWF, Vodafone, Deloitte, and CERTH, combining enterprise engineering with cybersecurity R&D.
I like solving problems end to end — from architecture and threat modeling to implementation, hardening, automation, and production delivery.
