Technology and sharing knowledge has always been a passion of mine. I've been developing web applications since 1998 and general business applications since 1985.

I've been in the fields of manufacturing, telecommunications, publishing, and now healthcare. As a software engineer I've made a long career developing web applications with many modern frameworks and tools. Experienced in UNIX, Java, C, VB, Ruby, JavaScript, SQL, Web Services, etc.
