About

A bit about me

I'm a Platform Engineer with a focus on building internal developer platforms, cloud infrastructure, and the tooling that helps engineering teams move faster and more safely. I care deeply about reliability, observability, and developer experience — the invisible foundation that great products are built on.

I work across the full infrastructure stack — from designing cloud architecture and writing Terraform modules, to building CI/CD pipelines, managing Kubernetes clusters, and setting up monitoring that actually pages the right people. When I'm not building infrastructure, I'm usually automating whatever I just did manually.
