Dad. Husband. Software. Hardware. Radio. Guitar.


I’m a Husband and Father of 2 Beautiful Girls who lives in Colorado. My background is in Computer Engineering and I’m interested in all things involving Software and Hardware. I’ve always geeked out on radio, and what I mean by that is anything that wirelessly sends an RF signal. One of my hobbies I’d also like to blog about is Guitar. More to come soon. The opinions in this blog are my own and don’t represent that of my current, or past employers.
