Linux System Administrator with 4 years supporting production VPS infrastructure, server hardening, and automation for crypto exchanges.

What I'm looking for

I’m actively seeking remote SystemAdministrator (Linux) or DevOps/Tech Support positions where I can secure production infrastructure, automate deployments with Ansible, and deliver strong troubleshooting for VPS, mail, VPN, and integrations.

I’m a Linux SystemAdministrator with 4 years of hands-on experience supporting production VPS infrastructure for a crypto exchange project. I specialize in server hardening, automation, troubleshooting, and secure mail/VPN services—focused on keeping systems stable under real-world pressure.

In my work, I manage software updates, security hardening (UFW, Fail2Ban, Nginx configuration, SSH key authentication), and protection against attacks. I automate server initial setup and configuration using Ansible, significantly speeding up deployments, while also handling backups (SCP, Rsync), scheduled tasks (Cron), and MySQL database management.

I also configure and maintain email services with SPF, DKIM, DMARC, and migrate mail archives using IMAPSync. On the connectivity side, I set up and support VPN solutions (Amnezia, VLESS, SOCKS5 proxy), and I develop and maintain production Telegram bots integrated with web APIs—running stably for 6+ months—and a Telegram Mini-App currently in testing.
