    Programming is my life and my language. My brother knew I was a programmer before I did. He bought me that first book when I was about 10. That was 23 years ago. I am a programmer with experience in many languages, platforms, and operating systems. I love working with small companies and startups. Whether you need someone to lead your team, program into the wee hours of the night, or just need someone to talk to, I can help. I have always enjoyed the challenge of creating interactive software. With the birth of the modern Internet, I found a new love in web development and web programming.
