Teoman Y.

Hi! I'm Teoman. I currently work as a full time DevOps Engineer for the Ministry of Interior. My main responsibilities include: - Managing Kubernetes Clusters that vary from development, staging to production. I also hold the CKA certificate. The applications run on the cluster are Java microservices, infrastructure related applications such as internal packaging systems (plugins, image registries), deployment related applications such as ArgoCD and GitLab runners and so on. I manage Big Data Engineering Kubernetes clusters that host Spark Applications, NiFi clusters, Trino backends, etc. - GitLab CI/CD pipelines where as a DevOps team, managing more than 50 projects and tracing every pipeline 24/7, creating smooth deployments that are being used by the whole country. - Managing infrastructure as code where I make calls affecting hundreds of Linux servers including production servers, tracking changes with Git. - Monitoring the running infrastructure where this many servers need to be intervened immediately in case of any failure, in which I rely on Grafana Prometheus Loki stack which again deployed on Kubernetes and bare metal, with many instances running on many networks collecting logs and metrics. I'm a Linux user since 16, and a professional administrator for 3 years now. Would be glad to be of your service, Thanks
