About Halfdan Harring
Halfdan Harring is a full-stack developer from Aarhus, Denmark. He builds apps, web apps, SaaS products and digital tools, and works across the whole product — from idea and interface to backend and release.
Based in Aarhus, Denmark, his current work centres on shipping real products. That means mobile apps, web apps and SaaS platforms built with a small, modern toolchain and a bias toward simple, usable software.
His approach is practical: start with a clear problem, build a focused first version, put it in front of real people and iterate. Several of his products — including HeadToHead, LostLead, TaskMondo, Dealer ID, Quiz Fight and Runish — come out of this way of working.
Halfdan works with an AI-assisted development workflow, using tools such as Cursor and ChatGPT to move faster from idea to working software, while keeping ownership of the architecture and the details.
Alongside building products, he speaks about software development, AI-assisted product building and entrepreneurship. His Danish talks are collected at ForedragMedHalfdan.dk.
