I'm a frontend developer in Hanoi, working my way over to the backend: learning Go, keeping the Kubernetes I studied for the CKAD in use, and running a home lab as the place to practice real infrastructure. I write about what I learn along the way. If you're a JavaScript developer picking up Go, setting up VLANs and DNS at home, or building a Hugo site without a theme, the posts here walk through exactly that, config files included. This site runs on Hugo + Cloudflare.

Viettel would not put its weak ONT in bridge mode, so I replaced it with a DFP-34X-2C2 GPON stick in my MikroTik. Every flash field the ALU OLT checks.
How I use Caddy and one wildcard cert to give every service in my homelab a friendly hoanghiep.dev name, with the header and mount gotchas I hit along the way.
A single docker-compose stack — Prometheus, Loki, Grafana, Alertmanager — watching every host, container, and network device in my homelab.
A docker-compose file for AdGuard Home, why its ports look strange, and why I run two of them on named volumes.
Splitting one flat home LAN into six VLANs on a MikroTik router, with a default-deny firewall for guest and IoT traffic.
How this blog's Hugo project is structured, without a theme, and how it deploys to GitHub Pages on every push.
First post — why I'm starting this blog and what I plan to write about.
