Close the loop: verification and heartbeat for AI coding agents
Agents must verify their own work — but the shape of that loop depends on what you're building. Solo work versus team-scale, runners versus workflows.
Writing on AI, engineering leadership & the craft
Hello, I'm Andrew. An engineering leader and builder.
Two decades building software and the teams that build software — currently in digital healthcare, working on what AI changes about the craft. 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.

A short introduction.

Engineering leader, writer
I've spent the better part of two decades building software and the teams that build software — currently leading engineering at a Swedish healthtech preparing for IPO, where the fun part is shipping AI into healthcare without breaking the things that make it trustworthy.
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.
