David Guest

Solution Architect and Technology Evangelist

As ThirdSpace’s Solution Architect and Technology Evangelist (yes, he knows it’s a long title), Dave has a background in IT that goes back to installing a piece of kit called a Microsoft Softcard in Apple 2e systems.

Dave has worked with technologies from Novell, IBM, Oracle and Microsoft on a variety of different projects and scales.

He is responsible for putting together solutions around identity and cloud services, and making sure that customers understand the current trends around identity in the cloud (and on-premises). Much of that includes presenting to large and small audiences and trying to turn technobabble into something resembling English.

Outside of work, Dave enjoys sport – specifically skiing, roller hockey, football, running (slowly), cycling – and he has an interest in history (don’t ask about the suit of armour in the garage).
