Oisin Grehan’s Summary

Owner Nivot Inc, independent consultant and software developer architect; over 12 years' experience in the Web industry. Currently Microsoft MVP (2008) for Windows Server Admin Frameworks (PowerShell).

My first foray into internet technologies began in the mid-nineties, when I built Ireland’s first large-scale eCommerce system for Allied Irish Banks (known as First Trust in North America). Programming is a passion for me, and I enjoy high-pressure environments and the company of talented colleagues to inspire me.
