About Me
Building Secure & Scalable Solutions
I'm a DevSecOps Engineer with a strong full stack development background, passionate about building secure, scalable infrastructure and modern web applications. Currently working at European Dynamics, I specialize in Kubernetes orchestration, CI/CD pipeline development, and cloud-native technologies.
With a Master's degree in Computer Science from the Technical University of Crete, I combine academic knowledge with practical experience. I've published research on publish-subscribe systems and have hands-on experience with modern DevOps and cloud technologies.
My hands-on experience as a full stack engineer gives me a deep understanding of the developer perspective - allowing me to design security and infrastructure solutions that fit naturally into development workflows rather than slowing them down. I'm passionate about automating workflows, implementing security best practices, and creating efficient solutions that make a real impact. When I'm not coding, I enjoy mentoring students and contributing to open-source projects.
