Writing
Long-form writing I keep as living documents, published as separate sites.
These are personal notes. The views expressed are my own and do not necessarily represent those of my current or past employers.
Main notes
Judgment at Scale
How technical judgment changes as scope grows from code to systems, platforms and organisation-wide decisions. Claims are stated so they can be wrong, each with a confidence level and the evidence behind it, alongside playbooks, worked cases, incident reviews and research notes.

Companion handbook
Modern Systems Architecture on AWS
AWS as the implementation lens, not the subject. A structured reference for learning, deciding, reviewing and applying architecture. A reference, not original research.
