With a background as a digital designer and more than 15 years of programming experience I have helped companies launch digital products in wide range of categories. From WordPress sites to highly specialized websites, web- and mobile apps built from the ground up.

My skills are focused around front-end development and JavaScript, but I work fluently with everything from UX and digital design to back-end and mobile development.

The last 3 projects

“You are never better than your last project” ..however I have chosen to highlight my last three project as they provide good examples of my work.

Ejendomstorvet.dk App


React Native development

Just finishing a large React Native project. The app allows users access and filtering of an extensive database on the go. The app integrates Google Maps and point clustering libraries to display location based data sets.

React Native was used as a platform to speed up development and to have as much shared code across platforms as possible.

A personal note

Originally from the west-coast of Denmark but living in Copenhagen since 2001. I have been using the computer as a creativ outlet since the Commadore 64 and still consider myself to be most of all a digital media craftsman.

I enjoy running, sailing, concerts and festivals.. and the occational IPA in my favorite Nørrebro bars.
