Hi 👋, I'm Simon

Pronouns: He/Him

I'm a platform architect working in regulated financial services, having started out in utilities. Outside the day job, I'm a CNCF Ambassador, co-chair of the CNCF Cartografos Working Group, and co-author and maintainer of the Cloud Native Maturity Model. I served as Track Chair for Platform Engineering at KubeCon + CloudNativeCon Europe 2026.

My community work focuses on three things: helping newcomers navigate cloud native, helping the community communicate its business value, and contributing technically to the platform engineering community.

Happy to talk about cloud native maturity, platform engineering in regulated and enterprise contexts, or running CNCF events.
