I build the layer beneath the product.

Cloud engineer and architect building reliable platforms with OpenStack, Ceph and Kubernetes. 5 years on private cloud infrastructure.

01 · Focus

Systems I like to own

[01]

Kubernetes

Container platforms that teams can ship onto without thinking about the cluster underneath.

[02]

OpenStack

Private cloud control planes, run and upgraded with confidence instead of fear.

[03]

Ceph

Software-defined storage with clear failure domains and a data path you can reason about.

[04]

Linux

The foundation under all of it: kernels, networking, and systems that stay legible.

02 · Writing

Notes from the platform layer

Everything a post can render

A Ceph storage fabric with dual-leaf redundancy

Operating OpenStack without fear

03 · Principles

Calm infrastructure is designed, not discovered

Make failure domains visible

Know what breaks together before it does.

Prefer boring upgrades

Small, rehearsed, reversible steps beat heroics.

Make the system legible

If the next engineer can't read it, it isn't done.

Have a platform problem worth mapping?
