I build cloud platforms on Kubernetes, web servers in Rust, and the interfaces people use on top of them.

About

Backend, frontend and the cluster underneath.

I'm a full-stack engineer who likes owning a feature from the database to the pixel. I've spent fourteen years shipping web applications in Java, Spring and React, led front-end teams, and lately I work deep in Kubernetes: distributed platform features, controllers, CI/CD and the console on top. On the side I write Rust and publish open-source tools other people actually install.
