About Me

DevOps Engineer with hands-on experience architecting and maintaining cloud-native infrastructure across AWS and Azure. Certified Kubernetes Administrator with a proven track record of implementing reliable CI/CD pipelines, optimizing system performance, and driving operational excellence in production environments.

I combine strong technical expertise with effective collaboration skills to deliver scalable solutions that align with business objectives. Passionate about infrastructure automation, observability, and continuously improving development workflows through modern DevOps practices.

My Background

Based in Athens, Greece, I earned admission to the prestigious National Technical University of Athens (NTUA), where I'm pursuing my MSc in Applied Mathematics and Physical Sciences with focus on Applied Mechanics, Computer Simulation, and Mathematics for Informatics.

Since 2016, I've built a diverse career spanning infrastructure support, DevOps engineering, and cloud architecture. My experience ranges from managing critical infrastructure for Athens Metro systems to implementing modern Kubernetes-based solutions for enterprise clients. This combination of academic rigor and real-world experience has shaped my approach to solving complex technical challenges.
