More About Kirk

Kirk Liemohn started out on UNIX, but transitioned to Microsoft technologies and has about 20 years on the Microsoft platform including .NET from its inception. He has done most of this as either a development lead or architect, with a large percentage of that time on SharePoint.

His focus over the last several years has included SharePoint migrations, Office 365 & Azure architecture and development, and integrating SharePoint with third party products. These solutions compliment Kirk’s passion around SharePoint enterprise search and customizing SharePoint to host divisional or enterprise-wide applications.

For a deep dive on SharePoint integration that covers the many areas Kirk is passionate about, check out the white paper Kirk co-authored: Benefits of SharePoint 2010 as a Product Platform.
