Hi, I’m Gerlin Nolasco — the person behind GnTech.

GnTech is my personal tech space where I document, test, and share practical knowledge about networking, homelab infrastructure, servers, virtualization, automation, cybersecurity basics, and self-hosted services.

This blog is focused on real-world learning. Most of the content comes from things I personally build, break, fix, and improve in my own lab environment.

My goal with GnTech is simple: create useful technical notes, guides, and project write-ups that can help others understand complex topics in a clear and practical way. I believe the best way to learn technology is by building it yourself. That is why this blog is not just theory — it is based on hands-on experience, troubleshooting, and continuous improvement.

What You’ll Find Here

  • Networking & Routing — MikroTik RouterOS, VLAN segmentation, IPv6, GPON/FTTH
  • Virtualization — Proxmox VE, container orchestration, VM management
  • Self-Hosting — Docker services, Cloudflare Tunnels, monitoring stacks, backup strategies
  • Security — Firewall design, VLAN isolation, IoT hardening, secure remote access
  • Automation — AI-assisted ops, scripting, Telegram bots, cron workflows
  • Infrastructure — Linux and Windows Server, storage, rack hardware, cabling

The Homelab Stack

  • Router: MikroTik hAP ax S (R1) — Edge gateway, ROS 7.22.1
  • Wi-Fi / Switch: MikroTik hAP ac² (R2) — Secondary AP, downstream switch
  • Servers: Proxmox cluster: G3 (i5-7500T), G4 (Ryzen 2400GE), G1 (i3-4030U), H1 (Xeon E-2276G remote)
  • Containers: Docker, LXC
  • Automation: OpenClaw Gateway (Zeny IA)
  • Monitoring: Uptime Kuma, Grafana dashboards
  • Cameras: Frigate NVR, Tapo C100
  • VPN: WireGuard via MikroTik DDNS

About This Blog

This site runs on Hugo with the PaperMod theme, served through Cloudflare Pages.

The interesting part? Posts are drafted automatically by an AI assistant (Zeny IA) every morning at 07:00 AST. A new topic is picked based on what’s already covered, the draft is written with proper Hugo front matter, verified with a clean Hugo build, then sent to my Telegram with inline Approve/Skip buttons. If I tap Approve, it commits and deploys automatically.

This is both a blog and a living experiment in AI-assisted infrastructure documentation.
