About Me
I help teams ship faster by designing and automating cloud-native infrastructure. With 12+ years of hands-on experience, I build production-grade Kubernetes platforms and CI/CD pipelines that are secure, observable, and cost-efficient鈥攐n both cloud and on-premises.
My toolkit includes Kubernetes (GKE/EKS/AKS/Rancher RKE2), Terraform, Helm, Jenkins, GitLab CI, and Argo CD. I architect and operate multi-cloud environments across Google Cloud Platform, AWS, Microsoft Azure, Yandex Cloud, DigitalOcean, and OpenStack, with strong focus on networking and security (e.g., Cloud Armor/Cloudflare) and end-to-end monitoring (Prometheus, Grafana).
What I deliver: reliable releases, automated recovery, and Infrastructure as Code your team can own. Whether you need a green-field platform, a migration, or cost and performance optimization, I help you scale with confidence.
Experience
FLO Teknoloji A.艦.
Sr. DevSecOps and Platform Engineer
2023 - Today
Designed, built, and operated platform services across multi-cloud (GCP, AWS, Yandex Cloud, Azure). Owned Kubernetes end-to-end on Linux; ran multi-cluster operations with Rancher, and standardized releases using Helm/Helm Charts and ArgoCD (GitOps). Automated Docker-based CI/CD workflows in Jenkins; implemented reproducible infrastructure provisioning with Terraform (IaC) and configuration automation with Ansible. Improved observability and on-call readiness with Prometheus + Grafana and ELK, including alerting rules and runbooks. Designed autoscaling with KEDA; supported Kafka/RabbitMQ operations. Contributed to Metabase integrations. Accelerated ops via SSH, shell scripting, gcloud tooling, and Python; embedded security controls (secrets, RBAC, baseline hardening) into pipelines and platform layers.
