About

The person behind the posts.

I'm Sean Lobjoit, a cloud and AI practitioner with deep expertise across the full modern tech stack. I work at the intersection of cloud infrastructure, artificial intelligence, and engineering leadership.

I founded Perpetual Squared to help organisations cut through hype and build systems that actually work: at scale, securely, and without burning budget.

This site is where I publish the thinking I share on LinkedIn: no-fluff takes on cloud strategy, AI architecture, platform engineering, and the decisions that separate good systems from great ones.
