Your Linux server is down, misconfigured, or leaking security gaps - I'll fix it fast and make sure it stays fixed. I specialize in setting up and hardening production Linux environments: VPS configuration, Nginx + SSL, Docker deployments, automated backups, and monitoring with Prometheus & Grafana. I don't just apply fixes - I document everything so you understand what changed and why. What I can help you with: → VPS setup and security hardening (SSH, firewall, fail2ban) → Nginx configuration + SSL certificates (Let's Encrypt) → Docker containerization and deployment → MySQL / PostgreSQL setup and maintenance → Monitoring and alerting (Prometheus + Grafana) → Incident troubleshooting and root cause analysis I've resolved 40+ real-world Linux failure scenarios on SadServers (Master certificate), built production-ready server environments from scratch, and completed a full DevOps lab covering Docker, Kubernetes, ArgoCD GitOps, and Prometheus monitoring. I respond quickly, communicate clearly, and document my work. If you have a server issue or need reliable Linux infrastructure set up properly - send me a message.
