Sysadmin

System Administration Portfolio

Reliable infrastructure is the foundation of any good web project. I provide complete system administration services — from setup to optimization — for Linux-based environments.
Key areas of expertise include:

• Server setup and configuration: Nginx, Apache, PHP-FPM, MySQL, Redis, Docker
• Control panels: HestiaCP, Plesk, cPanel, and custom setups
• Security and monitoring: firewalls, SSL, fail2ban, log management, backups
• Performance tuning: caching layers, load balancing, resource optimization
• DevOps & automation: shell scripting, cron-based jobs, CI/CD

I ensure servers are secure, stable, and ready for production — whether for personal projects or high-traffic enterprise systems.

I was involved in installing and setting up various server configurations running Linux operating systems, in particular Debian, Ubuntu, Centos. For example, I set up servers for web developers, where services such as Apache and Nginx are used. I also have experience setting up mail systems based on Postfix and Exim. For enterprises, I set up backup servers, in particular Proxmox Backup Server, CRM systems, etc.
