About me

I am a full time consultant specializing in problem solving. With a broad knowledge base and unique thought process, I approach projects with a passion not commonly found. While I admit a love for Open Source Software, do not think I am limited to it. I am a Microsoft Certified Systems Engineer, and Charter member MCSA because of my participation in Microsoft's beta program. Whether you need someone onsite, remote, or just for those emergencies, I am just a call away.
