Available to hire
I’m Dmitry Plekhanov, a Senior DevOps / Cloud Engineer / SRE with over 20 years of experience in Linux systems administration, cloud infrastructure, and automation. I specialize in building high-availability, high-traffic web platforms (1M+ daily users) and I bring hands-on expertise with AWS, Kubernetes, Terraform, Ansible, CI/CD, and performance tuning.
Based in Milan, Italy, I’ve helped migrate legacy infrastructures to cloud-native solutions, built scalable, secure environments, and optimized pipelines for reliability and speed. I’m fluent in English and Russian, with Italian at a beginner/intermediate level, and I enjoy collaborating with cross-functional teams to tackle challenging engineering problems.
