Hello 👋
I’m Etienne, a freelance engineer based in the Netherlands helping teams build, secure, and operate reliable cloud-native platforms at scale. I work at the intersection of platform and cloud infrastructure engineering, developer experience, operations, and security.
I’m also a member of the FikaWorks Collective, a collective of engineers focused on cloud-native solutions. We work together as a community to help businesses adopt scalable, resilient cloud platforms using CNCF technologies.
