My Goal

Developing computer software has been my career and hobby, and I enjoy sharing my work with you. While the main focus of this web site is the applications I develop, I want it to be more than just a software repository or "sales" site. This site must provide content that is educational, informative, and that will serve as a technical resource for people with similar interests.

To that end, I created a technical articles page with information, tips, and tricks in a "blog like" format. These articles share some of the ideas and techniques that others will benefit from. I have also created a page of technical resources related to ham radio and computer programming that I know you will find informative.
