I’m a software engineer based in London, but originally from the Netherlands. In the last couple of years I have mostly focused on version control, software distribution and networking (L3 and up).

At the moment, I am working as a Senior Staff Site Reliability Engineer at Aiven.

Between April 2021 and August 2022, I worked as Principal Site Reliability Engineer at Cognite.

Between February 2013 and March 2021, I worked as a Senior Site Reliability Engineer at Google in London, mainly on the authoritative DNS servers and other kinds of frontend infrastructure.

Between 2009 and 2012 I worked at Canonical Ltd., on Launchpad, Ubuntu, Bazaar and various cloud-related projects.
