Writing on AI, engineering leadership & the craft

Hello, I'm Andrew. An engineering leader building at the intersection of AI, teams, and strategy.

This is where I publish what I learn — field notes on agentic coding, high-performing teams, and what "done" means when the agents write most of the code. Occasionally in Swedish, when the story demands it.

How I Work With AI Agents — A "Stage 3" Field Guide

About

A short introduction.

Andrew Crookston
Engineering leader, writer

I've spent the better part of two decades building software and the teams that build software — currently leading engineering in digital healthcare, where the fun part of the job is shipping AI into a regulated environment without breaking the things that make it trustworthy. The specifics live on the résumé.

This site is where I think out loud. Expect field notes on agentic coding, post-mortems on interesting failures, and the occasional Swedish-language piece when the story demands it. Not a content mill. No newsletter pop-up. Just writing, filed when it's ready.
