PayPal, Site Architect

Glendale, AZ 85305 USA

 

I've had a passion and sometimes addiction with computers for as long as I can remember. I used my first Mac at age 5, taught myself to type at age 9, wrote my first web page at age 12, became a Linux admin at age 14, a Unix Admin and Cisco Engineer at age 16, and have been programming in Perl and PHP since I was 17. Today I am Site Architect for one the of the largest online payments companies in the world. PayPal, where I have worked since August 22nd, 2005 doing administration and now architecture.

For as far back as I can remember, I knew what I wanted to do. Ever since I saw my first computer it was love at first site, all my drive, ambition, and motiviation have propelled me ever since. I am an extremely positive, intelligent, and outgoing indiviudal who loves learning, music, programming, dogs, and working out. I get along with everyone, and regardless from the sound of my resume I am humble.

In my spare time I run TuxLabs where I keep in touch with cutting edge open source solutions. Additionally, I use the environment as a development playground and place to try out new concepts or business ideas. All of this is a bi-product of continuing my education as a student of life long learning.
