I'm a Windows developer with a background in Commodore 64 and DOS programming and some experience in Unix and CGI development. I started writing BASIC on paper back in 1985. At that time I didn't have access to a computer. My first machine was a Commodore 64. Since 1997 my main development is with Aivosto Oy.
This is a list of programs I have developed for public or professional use.

My other programs have been primarily for private use. They're mostly small utilities and simple games, such as genealogical databases for both humans and horses, a self-learning program for language students, a program to generate mazes, several formula race games and windowing user interface frameworks for both DOS and Commodore 64.
These are the programming languages I've written my programs in. In addition, I read about 20 other languages at a basic level.
