I specialize in high-stakes infrastructure recovery for Linux environments. My focus is on immediate, "Break-Fix" scenarios where downtime is costing you money. I do not maintain a public portfolio of code. I maintain Uptime. My background is in resilient system architecture—building and securing Linux environments designed to recover instantly. If your server is down, your SSL certificate is broken, or your Nginx config is in a loop, I don't waste time on documentation. I know the kernel. My only deliverable is a working server. Core Services: Disaster Recovery: Resolving boot loops, kernel panics, filesystem corruption, and 502/504 Bad Gateway errors. Security Hardening: Mitigating active attacks, closing vulnerabilities, and configuring firewalls (UFW/iptables). Rapid Deployment: Spawning and securing VPS instances (AWS/DigitalOcean/Vultr) in minutes. Technical Stack: Distros: Arch, Debian/Ubuntu, CentOS/RHEL/Rocky Virtualization: Docker, KVM/QEMU Web Services: Nginx, Apache, HAProxy Security: SSL/TLS, Fail2Ban, SSH Key-Only Auth I operate with zero latency. Send me the SSH keys. I fix it. I leave.
