Greetings, I'm John Dumas and I've been a professional software developer since 1991 and an independent contractor since 1999.

I've done a great deal of cross platform work, primarily involving windows and unix. I'm fluent in C++, Java, Php and JavaScript and passable in many other languages. In recent years, I've done primarily web work with various database backends.

Below, you'll find my resume in html and pdf format as well as links to some of my open source efforts. They're fairly representative of my skills and give me an opportunity to somewhat repay the many nice people who made their code available to me when I first got into programming.
