    United States - Last active: 02/18/2013 - Tests: 6 - Portfolio: 9

    I am an IT consultant based in the Austin, Texas area who enjoys working with and leading small teams to success. My work is based on Five Rules: Rule #1: Technology should always serve the end user and the needs of the business. To the extent any technology/solution fails to satisfy this rule, it is a temporary solution and an opportunity for improvement. Rule#2: In business, I.T. is overhead; the less I.T. costs to setup and maintain, the more successful its support team was in choosing their solutions. Rule #3: Good solutions are well documented and easy to understand. "Undocumented genius" and "confusing solutions" are contradictions. Rule #4: When you don't know what you are doing, ask. When there is no one to ask: Backup, work neatly, take good notes and communicate with everyone involved. Rule #5: Complexity kills. Keep IT simple, keep IT clean.
