About Me:

System Administrator / Security Administrator / IT System Engineer

Throughout my long and varied career, I have designed, built and administered small business networks, LDAP, POS systems, websites, networked file systems and supported multiple remote users. In every position that I have held, I was the go-to technician for all of the IT needs in house, and involved in all aspects of IT Management.

I am also an information security researcher that loves solving problems with technology and spending my free time learning as much as I can about new technologies and ideas. Building, breaking and fixing computer systems to solve problems and continuously learn is what I do for work, and for fun.

I'm seeking opportunities in an information security/technology related position such as: Security Administrator, Staff Technologist, Director of Information Technology, Endpoint Security Administrator, or Systems Administrator. These positions best utilize my knowledge, skills, leadership and talents while furthering long term career goals in the areas of expertise I'm most passionate about.
