Full Stack Developer Linux Sysadmin
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.

Veelgestelde vragen
Q: What access do you need?
A temporary SSH user with sudo access, or SSH key access. You can remove it as soon as the job is done.
Can you fix it if I don't know what's wrong?
Yes. Describe what you see (error message, screenshot), and I'll diagnose the problem before fixing it.
What if the problem is bigger than one issue?
I'll explain what I found and recommend the right package before doing extra work, so there are no surprises.
Will my website go down while you work?
I take a backup first and keep downtime to a minimum. For risky changes, I'll agree a time with you in advance.
