Hi, I'm Greg.

AI Automation, Web and Mobile Development

I help companies solve IT problems with automated workflows and AI-assisted solutions — from one-off scripts to full web and mobile applications.

My main venture right now is nowa.dk, where I install AI automation in businesses at fixed prices. The daily articles on this site are written and illustrated by one of those automations.
