About

This blog collects practical notes from over a decade of Linux systems engineering and SRE work. Most posts come from debugging sessions, incident post-mortems, or just interesting rabbit holes I fell into while trying to solve a real problem.

Topics lean toward:

• Linux kernel networking, eBPF, and netfilter
• Container orchestration (Docker, Kubernetes)
• Observability with Prometheus, Grafana, and OpenTelemetry
• nginx, Caddy, and reverse proxy patterns
• Shell scripting, automation, and CLI tools

No affiliate links, no sponsored posts, no newsletter spam. Everything here is written in my own words, sometimes late at night after a difficult oncall page.
