Carlos Semeao | Linux & DevSecOps Apprentice ⚙️🔐

I build and document real-world labs focused on Linux hardening, Ansible automation, and secure remote access.
Each repository demonstrates infrastructure control, privileged access enforcement, and automation precision — aligned with remote-ready DevSecOps roles.

  • 🧱 Linux Infrastructure Hardening
  • 🤖 Ansible Automation & GitHub Ops
  • 🌐 SSH, Firewalls, VPNs (Tailscale), and Privileged Access Control
  • ☁️ Pursuing AWS & CompTIA Security+ Linux+ Certifications
  • 🧠 Documenting hands-on labs to validate technical mastery

🔧 Featured Projects

Project Description Tools
ansible-ssh-hardening Hardened SSH access using Ansible, fail2ban, and Tailscale VPN Ansible, SSH, firewalld, Tailscale
linux-storage-backup-lab LVM provisioning, rsync-based backup, and disaster recovery lab LVM, rsync, bash
linux-networking-lab IP configuration, firewall rules, routing, and SSH service validation nmcli, firewalld, nmap, sshd_config
