01 About
Infrastructure should be calm, observable, and ready to grow.
I help engineering teams ship quickly and safely by making the systems beneath their products reliable, scalable, and cost-efficient.
Across more than eight years in IT infrastructure, I've worked as a Technical Support Specialist, Linux System Administrator, Network Engineer, DevOps Instructor, DevOps Engineer, and Site Reliability Engineer. That path shaped a practical approach: understand the whole system, remove toil, and make the right information visible.
Today I work across Linux, AWS, GCP, Docker, Kubernetes, Ansible, Terraform, Jenkins, Prometheus, Grafana, and the tools around them. My mission remains simple: learn as much as possible, as deeply as possible.
Automate the toil
Turning repetitive operations into repeatable, auditable workflows.
Measure clearly
Using observability to make system health understandable and actionable.
02 Favourite stack
