About Me
Hey there, I’m Spiros, a Systems Administrator and a graduate from the Department of Informatics at the Ionian University.
After building a solid foundation in Networking (Cisco, MikroTik, Ubiquiti) and Systems Administration (Windows/Linux/MacOS), I am deepening my expertise in modern DevOps and automation practices.
Currently, I’m actively working with, and further exploring, technologies such as:
- Automation (Ansible/n8n)
- Docker Container Orchestration (Nomad/Kubernetes)
- Infrastructure Orchestration (Terraform)
- Pipelines (Jenkins)
- Cloud Services (AWS/OCI)
Technical skills are not the only area I have developed through my experience. My peers describe me as a valuable team member, who knows how to work under strict deadlines and still provide quality results.
