I build the platforms other engineers ship on.

I'm a platform engineer at Rothesay in London. I started on Solaris and AIX servers in Wrocław, moved on to Cloud Foundry and Kubernetes, and now also build small tools that let AI work safely with my own data.

About

I've spent more than twenty years keeping infrastructure dependable so the teams on top of it can move quickly. In Wrocław I looked after Solaris and AIX systems for Nokia Siemens Networks, Gigaset and IBM Global Services.

I moved to London in 2012. At Springer I built a platform on Kubernetes, Docker and CoreOS. At the Government Digital Service I was on the core team of GOV.UK PaaS, and at uSwitch I worked on a shared Kubernetes platform on AWS. From 2018 I was at Fidelity International, working on an in-house Cloud Foundry platform and driving its move from on-prem VMware to AWS with Terraform and Concourse. I joined Rothesay in 2022.

Outside work I write Go: Terraform providers, Kubernetes sidecars, MCP servers, and media tools for Plex and Sonarr.
