What I'm looking for

I seek a senior DevOps/cloud role where I can lead infrastructure automation, improve reliability, mentor teams, and work with modern CI/CD and container platforms.

I am a DevOps engineer with over 10 years of IT industry experience focused on infrastructure automation, configuration management, and system administration.

I have hands-on experience managing enterprise infrastructure across cloud platforms (AWS, GCP, Azure, ESDS), building CI/CD pipelines with Jenkins and GitLab, and implementing containerization with Docker and Kubernetes.

My background includes Linux administration (Red Hat, Ubuntu, CentOS), database operations (MySQL, MSSQL, MongoDB, Postgres), monitoring with Prometheus/Zabbix/Nagios, and security practices such as server hardening, vulnerability checks, and DDoS prevention.

I have led teams and ITIL helpdesk operations, supported 24x7 production environments, and hold certifications including AWS Solutions Architect Associate, HDPCA, and RHCE.
