02 About

About me

As a Senior Cloud Security Consultant at NVISO Security, I help clients across various sectors and regions to assess, improve, and maintain their cloud security posture and compliance. I have expertise in Azure, Microsoft 365, Kubernetes, and Microsoft Sentinel, and I utilize PowerShell and Infrastructure as Code (IaC) to automate cloud security tasks and solutions, enhancing cloud security posture and optimizing security processes.

I hold a Master's degree in Computer and Information Systems Security from the University of Piraeus, where I learned the theoretical and practical aspects of cyber security, such as cryptography, network security, web security, and digital forensics. I also have multiple certifications in information security, such as ISO27001 Lead Auditor. I enjoy learning new technologies and staying updated on the latest trends and challenges in the world of cyber security. I am passionate about creating innovative and high-quality solutions that meet the business needs and expectations of my clients. I am also a clear, articulate, and effective communicator who can present ideas in a user-friendly language and collaborate with diverse teams and stakeholders.

Two of my greatest passions are getting lost in the rhythm of traditional dance and exploring new corners of the world.
