DevOps Engineer

DevOps Engineer by day, YAML debugger by night. I help turn “it works on my machine” into “it works in production” by automating infrastructure, building CI/CD pipelines, and keeping cloud systems happy and scalable. I enjoy breaking things safely (in staging), fixing them properly (in prod), and writing about real-world DevOps lessons—what worked, what didn’t, and what I wish I knew earlier. If it involves Docker, Kubernetes, or reducing pager alerts, I’m probably interested.
