I will fix linux server issues, nginx errors, and SSL certificates
Mahrez Benhamad
About this gig
Is your production server down, throwing 502 errors, or showing an insecure SSL warning?
I am a Senior Cloud Architect specializing in Linux administration, Docker containerization, and advanced reverse proxies (Nginx, Traefik, HAProxy). When servers fail, you need an engineer who understands the entire stack from the application layer down to the infrastructure.
What I can resolve for you:
- Security: SSL Certificate installation, HTTPS enforcement, and firewall configuration.
- Troubleshooting: Fixing 500/502/504 errors, server crashes, and application deployment failures.
- Database Recovery: Resolving PostgreSQL bottlenecks, storage limits, and connection issues.
- Docker & DevOps: Fixing broken docker-compose files, container networking, and CI/CD pipeline bugs.
Let's get your architecture back online and running securely. Please message me immediately with your error logs or server symptoms.

FAQ
What information do you need to start troubleshooting?
To diagnose and fix the issue quickly, I will need SSH access to your server (IP, username, and password/SSH key). If the issue involves SSL or DNS routing, I may also need temporary access to your domain registrar or Cloudflare dashboard. Please send any recent error logs in your first message.
My website is showing a 502 Bad Gateway error. Can you fix this?
Yes. A 502 error usually means your reverse proxy (Nginx, HAProxy, or Traefik) cannot communicate with your backend application (like your Django or Flask server). I will investigate the server logs, restart the crashed services, and fix the underlying configuration breaking the connection.
Will I have to manually renew the SSL certificate you install?
No. I configure Let's Encrypt SSL certificates with automated background cron jobs. Your certificate will automatically renew before it expires, ensuring you don't face sudden security warnings or downtime in the future.
Do you troubleshoot Docker containers that are crashing or won't start?
Yes. I can debug broken docker-compose configurations, fix container networking issues, resolve volume permission errors, and check the internal container logs to get your containerized applications running smoothly again.
What happens if my server is completely compromised or requires a massive overhaul?
My priority is to stabilize the immediate crisis and get your system back online. If I discover that your server requires a complete architectural rebuild or database migration for long-term stability, I will provide a detailed technical report and we can transition to a custom cloud architecture pr
