About

Professional summary

I’m a DevOps Engineer at Key to Trading in Limassol, responsible for cloud infrastructure, business-critical systems and SaaS platforms across AWS, Microsoft Azure, Microsoft 365 and Cloudflare. My work centers on CI/CD with GitHub Actions, Infrastructure as Code, and the monitoring and alerting that support fast incident detection and response.

I bring more than five years of hands-on infrastructure experience, from ISP network engineering at Prime-Tel and network operations at Equiti Group to systems administration across multi-cloud and virtualized environments. Alongside the technical work, I translate stakeholder requirements into user stories, prioritized backlogs and clear acceptance criteria, keeping delivery aligned with business, operational and compliance goals.

Expertise

Core competencies

Cloud & platform operations

Running AWS, Azure, Microsoft 365 and Cloudflare environments: DNS, networking, access control and security configuration for business-critical systems.

CI/CD & automation

GitHub Actions workflows and Python/Bash scripting for service deployments, infrastructure changes and recurring operational tasks, with less manual work and more consistent delivery.

Infrastructure as Code

Standardized, repeatable cloud and platform environments with Terraform and Ansible: changes made through code rather than consoles, and less configuration drift.

Monitoring & incident response

Monitoring and alerting across infrastructure, services and applications, plus hands-on incident investigation with internal teams and providers.

Networking & security

A network engineering background (ISP access networks, Cisco Meraki, MikroTik) applied to cloud networking, DNS and access controls.

Delivery & planning

Turning stakeholder requirements into user stories and technical tasks, prioritizing the backlog and defining acceptance criteria.
