Hire the Best Zabbix Specialists

I keep business-critical systems running on Linux servers. Twelve years of experience. I cover a range of services, but it's really one discipline: infrastructure, that stays up. WHAT I DO Linux server administration. VPS setup, hardening, performance tuning, recovery, and ongoing care on AWS, DigitalOcean, Hetzner, Vultr, cPanel/WHM and others. Firewalls, SSL, backups, monitoring. The boring work that keeps everything else possible. Self-hosted automation and AI infrastructure. I deploy n8n on hardened Linux servers (Docker, reverse proxy, SSL, automated backups) so you own your automation instead of renting it. I also build private AI stacks with Ollama, OpenWebUI, and local or API-connected LLMs, for teams that want AI capability without handing their data to a third party. Website and email migrations. Files, databases, DNS, SSL and mailboxes moved cleanly between hosts. Hundreds completed over the years. The rule is simple: nothing breaks, nothing goes missing. WordPress and phpBB. Installs, fixes, malware cleanup, upgrades, long-term care. I've been a go-to phpBB specialist on Upwork for years, including an 18-month engagement keeping a production community forum healthy. WHY CLIENTS STAY Most automation specialists build on cloud platforms you don't control and can't leave. I build on infrastructure you own. Your server, your data, your system. And I treat it the way a sysadmin should: monitored, backed up, documented, and maintained so it keeps running after I hand it over. 100% Job Success across 149 jobs, repeat clients going back years, and work ranging from small business rescues to a LAMP/REST API deployment on AWS for an Upwork enterprise client. HOW I WORK I scope honestly before we start. If something is outside what I do (app development, SEO, design) I'll tell you upfront. Hourly with the Upwork tracker for open-ended work. Fixed price when the scope is tightly defined. If something I set up breaks within days of handover because of my work, I fix it for free. I'm flexible with times. Can work when the it is best for your project, e.g. off-peak hours. If your server, site, forum or automation needs to work every day and not just on launch day, message me and tell me what's going on.
