Education

B.Sc. Computer Science, 2024 | MSc Security, AUEB (ongoing)

I graduated with a B.Sc. in Computer Science from the National and Kapodistrian University of Athens and am currently pursuing an MSc in Information Systems Development and Security at AUEB. I work as a Cloud DevOps Engineer at Performance Technologies, operating Azure infrastructure, managing AKS clusters, building CI/CD pipelines, and configuring ELK-based observability. My background in Linux, systems programming, networking, and distributed systems gives me the engineering foundations I am now extending into security — penetration testing, vulnerability assessment, secure network design, and cryptography — through MSc coursework, TryHackMe, and CryptoHack.
