About
Who I am
I’m Cristian Gómez — Platform Engineer specializing in Kubernetes networking and Linux internals.
Eight years running production SRE at a major bank in Mexico. The kind of environment where something breaks at 2 AM and you have 15 minutes before it affects millions of transactions. That’s where I learned what actually matters when packets stop moving — and why most networking problems look mysterious until you understand what’s happening at the kernel level.
Outside of work I practice Stoicism, suffer through FromSoftware games, and have a long-term plan to own a ranch and grow my own food.
“It is not that we have a short time to live, but that we waste a great deal of it.” — Seneca

What I’m building
The From Scratch series: Platform Engineering explained from the internals out, for engineers who want to understand why, not just how.
Every article starts where the abstractions end — at the Linux kernel, at the iptables rule, at the conntrack table. I build the concept by hand, trace the full packet path, map it back to what Kubernetes does under the hood, and close with a troubleshooting checklist you can actually use in production.
The companion lab repo — linux-networking-labs — has the hands-on implementations behind each article.
