Ngô Tấn Tài (Newnol)
I build secure, observable systems that withstand chaos and help teams respond faster. My happy place is somewhere between Linux terminals, packet captures, and automation scripts.
Incident Response & Forensics
Experienced in building playbooks, triaging alerts, and performing memory/disk analysis for capture-the-flag challenges and homelab exercises.
DevOps Automation
Deploying and hardening Docker/Kubernetes workloads, automating CI/CD pipelines, and enforcing observability across Linux fleets.
Secure Homelab Builder
Maintaining a Proxmox-based infrastructure with layered defenses ( Fail2Ban, firewall zones, centralized logging ) for realistic attack/defense simulations.
