Sachin G.

Red Hat Certified (RHCE since 2009) Linux & AI infrastructure engineer with 1,000+ server projects delivered. I set up, secure and fix Linux VPS and cloud servers, and deploy production-ready self-hosted AI and automation stacks (Ollama, Open WebUI, n8n) that stay private and safe. What I do: - Linux server setup, migration & performance tuning (Ubuntu, Debian, RHEL, AlmaLinux) - Server security hardening: firewalls, SSH, brute-force & bot protection, CIS benchmarks - Self-hosted AI & automation servers: Ollama, Open WebUI, n8n, AnythingLLM (deployment, hardening, monitoring) - Deploying AI-built apps (Lovable, Replit, Claude Code, v0) to a secure production VPS - VPS & cloud hosting: DigitalOcean, Hetzner, Contabo, Hostinger, AWS EC2 - Control panels: cPanel/WHM, HestiaCP, CloudPanel setup & migration - Docker & Docker Compose deployments - Web stack: NGINX, Apache, MySQL/MariaDB, PHP, WordPress hosting - Email, DNS & SSL: SPF/DKIM/DMARC, mail servers, certificates - Cloudflare: WAF, CDN, bot and AI-scraper protection - Emergency recovery: downtime, SSL/DNS errors, malware cleanup - Ansible automation & monthly server management How I work: 14+ years running production systems, plus 8 years training Linux and DevOps engineers as a Red Hat training partner. On your server that means: a backup before every change, your confirmation before I touch anything critical, a clear rollback path, and a written report when the work is done. No quick patches, no surprises. Whether you need a one-time emergency fix, a server migration, or ongoing monthly support, message me with your server details and I'll tell you honestly whether I'm the right fit.
