About
I keep systems reliable, observable, and understandable.
My homelab is where I test, break, fix, document, and learn.
I’m Nam, a Technical Support Team Lead and Linux Administrator based in Europe. I work across support operations, servers, networking, monitoring, and technical troubleshooting, and I use my homelab to keep learning beyond the job.
Whether I’m coordinating escalations, resolving production issues, or experimenting at home, my goal is the same: learn deeply, document clearly, and keep improving.
