Hi, I'm Alexander Chernov 👋

Staff Platform & Software Engineer with 20+ years building production systems — from distributed Go backends and Kubernetes operators to full observability stacks and GPU-aware schedulers. I care about systems that are reliable by design, not by accident.

Based in the UK.

What I work on

As a software engineer, I write production Go — Kubernetes operators, custom schedulers, CLI tooling, gRPC services, and infrastructure automation. I've contributed to and maintain several open source tools in the Kubernetes and Terraform ecosystems.

As an SRE / Platform Engineer, I design and operate observability stacks (Prometheus, Grafana, Mimir, Loki, Tempo, VictoriaMetrics), define SLOs and error budgets, build incident response automation, and own reliability across distributed multi-cloud environments. I've built platforms that others ship on, not just infrastructure for its own sake.

Open source

Project What it does Language
terraform-provider-kubectl Terraform provider for managing raw Kubernetes manifests via kubectl — used by teams who need finer control than the official provider Go
gitlab-runner-operator Kubernetes operator to manage GitLab Runner lifecycle on-cluster Go
terraform-application-argocd Terraform module for deploying applications into Argo CD HCL
Helm Charts Various Helm charts for open source projects Helm
