I make cloud-native systems reliable, secure and repeatable.

I design and automate Kubernetes platforms end to end, harden clusters, and build CI/CD pipelines that help teams ship faster. Everything I run is managed as Infrastructure as Code.

I work remotely from Amsterdam with clients in the Netherlands and Türkiye. M.Sc. in Information Technology from Yıldız Technical University (GPA 3.60), B.Sc. in Industrial and Systems Engineering from the National Defence University. Turkish native, English B1 to B2.

What I build

Kubernetes platforms

Production clusters on EKS, AKS, GKE and bare metal, with upgrades, autoscaling and multi-tenant access designed in from day one.

Infrastructure as Code

Terraform, Terragrunt, Ansible and CloudFormation. Reviewed, versioned, reproducible.

CI/CD and GitOps

GitHub Actions, GitLab CI, Jenkins, Argo CD and Flux. Small changes reach production safely, many times a day.

Observability and security

Prometheus, Grafana, Loki and ELK for signals you can act on. SonarQube quality gates and CKS-level hardening for regulated workloads.
