I'm a software engineer and pilot. I work at craigslist by day, hacking on various bits of back-end software and data systems. As a pilot, I fly Glastar N97BM, Just AirCraft SuperSTOL N119AM, Bonanza N200TE, and high performance gliders in the northern California and Nevada area.
I'm also the original author of "High Performance MySQL" published by O'Reilly Media. I still speak at conferences and user groups on occasion.
