DevOps Engineer at WOW Corporation, delivering AWS infrastructure and CI/CD pipelines, with public Kubernetes work on GitHub.

Message

At WOW Corporation, I maintain AWS infrastructure described in Terraform and configured with Ansible. I run GitHub Actions delivery pipelines with Docker image builds and Trivy scanning as a blocking gate.

I also administer Linux servers and NGINX, and monitor production with Prometheus, Grafana, and CloudWatch. When incidents involve Linux, DNS, TLS, containers, or databases, I document the resolution in Confluence.

At WOW Corporation, I shipped two JavaScript browser extensions through the Chrome Web Store for internal teams; one cut a routine lookup from 30 seconds to 2. I also wrote a Python desktop utility that replaced a manual process for those teams.

In my independent DevOps work, I built a Kubernetes cluster from scratch on virtual machines and delivered workloads with Argo CD and Helm. I’ve also written rebuildable AWS infrastructure in Terraform and Ansible, and built and still operate a live Node.js service.
