About

My Story

Since beginning my journey as in the IT industry more than 15 years ago I’ve had moved into several positions.  I started as an IT administrator, was promoted to MS SQL Coder and then developer.  I managed a large enterprise world wide network of more then 3,000 users but have also designed and developed networks as small as a hundred users.  The last several years I have been spending more time on building apps for the web and devices.
