Full-stack engineer who loves building tools that make other engineers' lives easier. I've spent the last decade deep in container platforms, networking, and infrastructure — automating the tedious, untangling the complex, and turning large-scale problems into straightforward solutions. Happiest as an IC, solving hard problems and shipping things that matter.
