Software Engineer / Ham Radio Operator / ...


I am a software engineer from Sweden who has worked with various web-based business systems since 2005.

I'm probably best known for running the APRS Direct website (and also the Glider RADAR website). I develop and maintain the software used to run these websites in my spare time.
