Linux and DevOps engineer — Nginx, Docker, CI/CD

Over nine years of working with production Linux servers I have brought order to dozens of infrastructures — from single VPS to multi-service stacks under serious load. I handle everything related to the server side of a web application: from a clean system installation to a state where you can just forget about the server and focus on the product. I always start with how your application actually behaves — how much memory it needs, how it handles traffic spikes, where the bottlenecks are — and only then tune the environment to that reality.

Most often people come to me tired of manual deploys, random downtime and servers whose design no one quite remembers anymore. That is the pain I close: I package services in Docker, set up CI/CD so a git push becomes a safe release, and connect monitoring that tells about a problem before users notice it. I lay down security from day one, not later — firewall, fail2ban, key access, regular scans. I return the server documented, hardened and predictable.

— Server setup: Ubuntu/Debian VPS from scratch to production-ready
— Nginx: reverse proxy, SSL, performance tuning, security headers
— Docker and Docker Compose: containerization, multi-service stacks
— CI/CD: GitHub Actions, GitLab CI, auto-deploy
— Hardening: UFW, fail2ban, SSH keys, ClamAV, rootkit detection
— Monitoring: Prometheus, Grafana, Netdata, uptime alerts
— Database administration: MySQL/PostgreSQL tuning, backup automation
— Cron and automation: scheduled tasks, log rotation, health checks
