About this Gig

Server down? Nginx 502s, expired SSL certificates, broken reverse proxies, Docker containers that won't start - I find the root cause from the logs and fix it.


Hands-on Linux engineer running my own home lab (soft router, NAS, Docker media stack) for years. I fix your server problem with evidence - logs first, no guesswork.


What I can do: VPS initial setup & hardening (SSH keys, firewall, fail2ban), Docker / Docker Compose deployments, Nginx reverse proxy & HTTPS, service crash diagnosis, disk-full rescue, backup automation, migration between servers.


How we work: you describe the symptom -> I diagnose from logs -> I fix it remotely (SSH or remote tool, your choice) -> you get a short report of root cause + what changed.
