Developer experience
at Homerunner

I bring developers’ data and tools together in one system, making it easier to find the information they need.

It integrates CodePipeline, Athena logs, Kubernetes, CLI tools and GitHub.

Internal tool. No public demo.

Components across
frameworks

I built the library as we started using more frameworks. It makes it easier to bring existing systems into our new visual language. It’s the project I’m proudest of.

The components are defined in plain CSS and detailed Markdown files. Packaged as a Claude skill, the library can be implemented with a prompt in whichever framework the system uses.

My games

For me, daily games are a way to keep my mind active. As AI becomes part of more everyday tasks, I enjoy a small challenge I have to solve myself.

Sortivio

Find connections between words and group them into categories. A new puzzle every day, in Danish and English.

About me

I start by working out what the task requires and what value a solution can bring. For me, a system succeeds when people use it and it makes their work easier.

I enjoy exploring new technologies and choose tools to suit the task. I also help people use Claude for development.
