About
Just a quick glimpse into who I am.
Background
Hello world, I'm Kassymkhan Kalzhan — a DevOps engineer specializing in Kubernetes, GitOps, and cloud infrastructure security, based in Almaty, Kazakhstan.
With 5+ years of experience designing and operating bare-metal and cloud Kubernetes platforms for blockchain and fintech infrastructure, I bring deep hands-on expertise in GitOps (ArgoCD), observability (VictoriaMetrics, Grafana, Loki), Envoy service networking, and secrets management (HashiCorp Vault).
I've reduced incident response time by up to 50% through an observability stack migration and sustained 99.9% uptime across 80+ revenue-critical blockchain nodes. My background in Information Security complements a security-first approach to everything I build.
Outside of tech, I enjoy reading about philosophy, filming creative vlogs, and experimenting with digital art and motion design.
