What I'm looking for

I seek an operations role where I can secure and optimize infrastructure, automate processes, collaborate with engineering teams, and grow into larger cloud and SRE responsibilities in a responsive, security-focused company.

I am a System Administrator with over five years of hands-on experience managing Linux and Windows servers across data centers and AWS cloud environments. I specialize in system hardening, performance optimization, automation, and compliance to ensure reliable, secure infrastructure.

In my roles I have managed global hosting, DNS, and email services, implemented disaster recovery solutions, and maintained 24/7 monitoring with Nagios and Zabbix to guarantee uptime. I routinely automate tasks with shell scripts and cron jobs to improve efficiency and reduce manual work.

I collaborate closely with developers, DBAs, vendors, and cloud providers to support deployments, troubleshoot complex issues, and recommend infrastructure scaling and cost optimizations. I have experience across Proxmox, KVM, AWS, Apache/Nginx, MySQL/MariaDB, and common control panels like cPanel and Plesk.

I am available for immediate joining and bring a practical, security-first approach to operations, backed by documented SOPs, access policies, and strong customer support experience across Tier-1 to Tier-3 levels.
