People hire me to help them scale their businesses.

I manage over 60 websites with thousands of daily visitors.

Starting in 1994 I ran my first paid online service. It was a dial in bulletin board system that users accessed via 2400 baud modems. Users actually sent checks in the mail for more access time. In 1995 Internet access finally became available in the small rural Texas area I was growing up in. Quickly I registered some domains and began hosting on some shell accounts on a BSD Unix system. Soon Linux was my primary operating system since the source was available, it was great for development and it was a true multi-tasking operating system.
