DevOps · Cloud Native Engineer
I narrow the gap between development and operations so teams can focus on business logic, not infrastructure. I started as a backend engineer (Kotlin · Spring Boot) and now build the platform those services run on.
- ☸️ Kubernetes platform — EKS with Karpenter, Istio ambient mesh, Cilium (eBPF), and Operators for stateful components
- 🏗️ Infrastructure as Code — AWS and Cloudflare managed with Terraform modules, deployed through GitOps (Argo CD)
- 🔄 CI/CD · Workflow — GitHub Actions (ARC), Argo Workflows, and self-hosted Temporal
- 🔐 Identity · Zero Trust — Keycloak, Okta SSO, OAuth2 Proxy, and Istio authorization policies
- 📨 Event streaming — Kafka, Kafka Connect, Debezium CDC, and Schema Registry on Kubernetes
- 📝 Writing — I only write about what I've actually run: comstering.github.io
Contributions
- bitnami/charts#35772 — Schema Registry: make the JKS secret optional so SCRAM-SHA-512 works with external MSK (merged)
- kafbat/kafka-ui#1205 — Messages: fix typos (merged)
Side project
- lomeone — side-project org on AWS, with all infrastructure managed in Terraform
