Over deze dienst

Is your website down, showing 502/504/500 errors, or "Not Secure"? I'll find the root cause and fix it fast.

I'm a Linux system administrator with 3+ years managing a 30+ server production fleet for a US e-commerce company, keeping 99.9% uptime.

What I can fix:

  • 502 Bad Gateway, 504 Timeout, 500 Internal Server Error
  • Nginx and Apache config, reverse proxy, port issues
  • SSL/HTTPS: Let's Encrypt, expired certificates, redirect loops
  • Network issues: DNS, firewall, blocked ports, timeouts
  • Server security: SSH hardening, UFW firewall, fail2ban
  • Docker and app deployment problems
  • High CPU/RAM usage and slow servers

Platforms: Ubuntu, Debian, CentOS, AWS, DigitalOcean, Kamatera, Hostinger VPS and more.

Why work with me:

  • Root-cause fix, not a quick patch
  • Clear report of what was wrong and what I changed
  • Safe access: a temporary SSH user you can remove anytime
  • Backup taken before any change

Please message me before ordering with a short description of your problem so I can recommend the right package.
