About me

Before I wrote code, I fixed trucks. As a wheeled vehicle mechanic in the U.S. Army, I learned to read technical manuals, find the real cause of a failure and fix it under pressure. That is still how I debug.

I studied multimedia design, then earned a master's in IT Management with a focus on information security. Today I run Bamboo Dragons, where I draw, design and build the software my own business runs on.
