Kubernetes, CI/CD, infrastructure as code, and the tooling that keeps production systems running smoothly.
Battle-tested patterns for running Kubernetes at scale — networking internals, IaC discipline, and observability foundations.
Terraform in production: state locking, module design, environment directories, and CI/CD guardrails that prevent resource destruction.
Definitive kubectl reference: pod debugging, deployments, StatefulSets, RBAC, scheduling, Helm, and production troubleshooting flowcharts.
Docker reference: container lifecycle, image management, volumes, networking, and debugging tools for production systems.
60+ Linux commands for production debugging: processes, networking, kernel tuning, and the gotchas that trip up engineers.
Production Git reference: core workflow, branching, history rewriting, recovery, and advanced operations compressed into lookup tables.
SLOs and error budgets: transforming reliability into organizational policy with Prometheus instrumentation and burn-rate alerts.
Master observability with real code: Prometheus metrics, structured logging with slog, and OpenTelemetry tracing to debug incidents fast.
How Kubernetes networking actually works — CNI plugins, kube-proxy iptables chains, the CoreDNS tax, and the debugging commands that find real problems.
