I work as a data center manager. I maintain multiple redundant data centers and staff to support enterprise Internet applications and back office infrastructures running Unix and Windows systems. I have knowledge of electronics and hold a General calls armature radio license. I have program computers for years and enjoy working on embedded system as a hobby. I started computer life as a assembler language program and I've worked on operating systems, languages and business applications. I enjoy astronomy, photography and painting in both watercolor and acrylics.
